test(T1): add edge-case coverage for EmailRepositoryImpl

Three new test groups bring the unit-test count from 54 to 57:
- concurrent moves: two simultaneous moveEmail calls complete without
  corruption and both changes are enqueued in pending_changes
- SMTP auth failure: sendEmail propagates a 535 authentication error
  thrown by a fake smtpConnect
- IMAP UID validity change: a uidValidity mismatch causes a full re-sync
  that wipes stale local emails and updates the checkpoint

Also extend _makeRepos() to accept optional imapConnect/smtpConnect
overrides, and import drift without the isNull/isNotNull symbols that
clash with package:matcher.

-# Implementation Plan: Secure WebView for HTML Emails (#21)
-
-## Goal
-Replace the current `flutter_html` based rendering with a hardened WebView-based approach to improve rendering fidelity while strictly enforcing security and privacy.
-
-## 1. Dependency Management
-- **Core**: `webview_flutter` (v4+)
-- **Linux Platform**: `webview_flutter_linux` (Official community-supported or WebKitGTK based implementation). *Note: I will verify the exact package name during implementation.*
-- **Utilities**: `url_launcher` (existing) for opening links in the system browser.
-
-## 2. Secure WebView Component (`lib/ui/widgets/secure_email_webview.dart`)
-Create a new widget `SecureEmailWebView` that encapsulates the `WebViewWidget` and its controller.
-
-### Configuration & Hardening
-- **Disable JavaScript**: `controller.setJavaScriptMode(JavaScriptMode.disabled)`.
-- **Background**: Match the application theme (e.g., transparent or surface color).
-- **Security Headers/CSP**: Inject a Content Security Policy via `<meta>` tag in the HTML wrapper:
-  - `default-src 'none'; style-src 'unsafe-inline'; img-src 'self' data:;` (Blocks all external assets by default).
-
-### Image Blocking Logic
-- **Initial State**: Block remote images by injecting a CSP that restricts `img-src` to `data:` and local schemes.
-- **Toggle Mechanism**:
-  - Provide a "Load Remote Images" button in the Flutter UI.
-  - When triggered, re-render the HTML with an updated CSP: `img-src * data:;`.
-
-### Link Interception & Phishing Protection
-- Implement `NavigationDelegate.onNavigationRequest`.
-- **Process**:
-  1. Intercept any URL that doesn't start with `about:blank` or `data:`.
-  2. Block the navigation in the WebView.
-  3. Trigger a Flutter `showDialog` for confirmation.
-- **Phishing Protection Dialog**:
-  - Show the full URL.
-  - **Bold the FQDN**: Parse the URL using `Uri.parse`.
-    - Example: `https://`**`important-bank.com`**`/login`
-  - "Open in Browser" button uses `url_launcher`.
-
-## 3. Integration Plan
-### Step 1: Initialization
-Modify `lib/main.dart` to initialize the Linux WebView platform (using `webview_flutter_linux` or similar) during app startup.
-
-### Step 2: Replace Renderer in Screens
-- **EmailDetailScreen**: Replace `Html(...)` with `SecureEmailWebView(html: body.htmlBody!)`.
-- **ThreadDetailScreen**: Replace `Html(...)` with `SecureEmailWebView(html: body.htmlBody!)`.
-- Remove `flutter_html` imports and dependencies once migration is complete.
-
-## 4. Verification & Security Audit
-- **Manual Tests**:
-  - Open emails with complex HTML layouts.
-  - Verify images are blocked initially.
-  - Verify "Load images" works.
-  - Click various links (http, https, mailto) and verify the confirmation dialog and FQDN bolding.
-- **Security Check**:
-  - Verify that `<script>` tags are not executed.
-  - Verify no network requests for external images occur before user consent (via DevTools or proxy).
-
-## 5. Potential Challenges
-- **Linux WebView Stability**: WebKitGTK on Linux can sometimes have rendering or sizing issues in Flutter.
-- **Scrolling**: Ensuring the WebView integrates smoothly into the `ListView` of the email detail screen (might require fixed height or `SizedBox`).

-# SharedInbox — Improvement Plan
-
-30 tasks across 7 perspectives. Priority markers: 🔴 high · 🟡 medium · 🟢 nice-to-have.
-
----
-
-## Group 1: Performance
-
-### P1 — Done: https://codeberg.org/guettli/sharedinbox/pulls/41
-
-### P1 🔴 Replace LIKE-based search with FTS5 virtual table
-The current `observeEmails` and search queries use `LIKE '%query%'` which becomes a full-table scan at scale.
-Create an `email_fts` FTS5 virtual table (subject, preview, fromJson) populated via trigger or sync-time insert.
-Wire `SearchScreen` to query the FTS table instead.
-Files: `lib/data/db/database.dart`, `lib/data/repositories/email_repository_impl.dart`.
-
-### P2 🔴 Lazy-load email bodies on scroll (pagination)
-`observeThreads` and `observeEmails` return the full list with no limit. As the mailbox grows this streams thousands of rows into memory.
-Add a page-size parameter (e.g. 50) with "load more" support in `EmailListScreen`.
-The `EmailBodies` table is already separate — never fetch bodies in the list query.
-Files: `lib/data/repositories/email_repository_impl.dart`, `lib/ui/screens/email_list_screen.dart`.
-
-### P3 🟡 Defer HTML parsing off the UI thread using an Isolate
-`flutter_html` parsing blocks the raster thread for large HTML bodies, causing jank when opening email detail.
-Move the HTML→Widget tree conversion (or at minimum the `html_utils.dart` HTML-to-plain step) into a `compute()` call.
-Files: `lib/ui/screens/email_detail_screen.dart`, `lib/core/utils/html_utils.dart`.
-
-### P4 — Done: https://codeberg.org/guettli/sharedinbox/pulls/36
-
-### P5 🟢 Cache the formatted date strings in EmailListScreen
-`DateFormat('MMM d').format(...)` is called for every email on every rebuild. Compute and cache these in the model layer or inside the list item widget's `build` method using a static cache map.
-Files: `lib/ui/screens/email_list_screen.dart`, `lib/core/utils/format_utils.dart`.
-
----
-
-## Group 2: Reliability & Resilience
-
-### R1 — Done: https://codeberg.org/guettli/sharedinbox/pulls/20
-
-### R2 — Done: https://codeberg.org/guettli/sharedinbox/pulls/22
-
-### R3 — Done: https://codeberg.org/guettli/sharedinbox/pulls/35
-
-### R4 — Done: https://codeberg.org/guettli/sharedinbox/pulls/23
-
-### R5 — Done: https://codeberg.org/guettli/sharedinbox/pulls/45
-
-### R6 — Done: https://codeberg.org/guettli/sharedinbox/pulls/24
-
----
-
-## Group 3: Security
-
-### S1 🔴 Optional SQLCipher encryption for the Drift database
-Emails cached locally are plaintext. Users on shared or rooted devices are exposed.
-Add an opt-in "Encrypt local storage" setting using `drift`'s `encrypted` backend (`sqflite_cipher` / `sqlcipher_flutter_libs`).
-Store the database key in `flutter_secure_storage` (already present).
-Files: `lib/data/db/database.dart`, `pubspec.yaml`, a new settings toggle.
-
-### S2 — Done: https://codeberg.org/guettli/sharedinbox/pulls/25
-
-### S3 🟡 Enforce certificate pinning for known providers (opt-in)
-Auto-discovered accounts for major providers (Gmail, Fastmail, Proton) could be pinned to their known CA hierarchy.
-Implement as an opt-in per-account setting; only applies when the account is auto-discovered via `AccountDiscoveryService`.
-Files: `lib/core/services/account_discovery_service.dart`, `lib/data/imap/imap_client_factory.dart`.
-
-### S4 🟢 Audit and restrict external link handling in HTML emails
-`flutter_html` passes `<a href>` clicks to `url_launcher` without a prompt.
-Before launching, show a confirmation dialog with the destination URL so phishing links are visible.
-Files: `lib/ui/screens/email_detail_screen.dart`.
-
----
-
-## Group 4: User Experience
-
-### U1 — Done: https://codeberg.org/guettli/sharedinbox/pulls/26
-
-### U2 — Done: https://codeberg.org/guettli/sharedinbox/pulls/27
-
-### U3 🟡 Add "Recent searches" history to SearchScreen
-The search bar clears on navigation. Store the last 10 search terms in a local DB table and show them as chips below the search field when the field is focused but empty.
-Files: `lib/ui/screens/search_screen.dart`, `lib/data/db/database.dart`.
-
-### U4 — Done: https://codeberg.org/guettli/sharedinbox/pulls/28
-
-### U5 — Already implemented (Dismissible archive/delete swipes with undo, found in email_list_screen.dart)
-
-### U6 — Done: https://codeberg.org/guettli/sharedinbox/pulls/29
-
-### U7 🟢 Onboarding walkthrough for first-time users
-The app opens directly to an empty account list with only a `+` button. First-time users have no guidance.
-Add a one-time welcome card or bottom-sheet with the three-step flow: Add account → wait for sync → open inbox.
-Files: `lib/ui/screens/account_list_screen.dart`.
-
-### U8 🟢 "Mark all as read" action in mailbox
-Power users managing high-volume mailboxes need bulk read marking. Add a "Mark all as read" option in the mailbox overflow menu.
-Files: `lib/ui/screens/email_list_screen.dart`, `lib/core/repositories/email_repository.dart`, `lib/data/repositories/email_repository_impl.dart`.

-
-## Group 5: Testing
-
-### T1 — Done: https://codeberg.org/guettli/sharedinbox/pulls/30
-
-### T2 — Done: https://codeberg.org/guettli/sharedinbox/pulls/31
-
-### T3 — Done: https://codeberg.org/guettli/sharedinbox/pulls/43
-
-### T3 🟡 Contract tests for all Repository interfaces
-The interfaces in `core/repositories/` have no shared contract test suite. Concrete impls can silently diverge.
-Add a shared `EmailRepositoryContract` abstract test class; run it against both `EmailRepositoryImpl` and any future mock/fake. Mirror this for `MailboxRepository` and `AccountRepository`.
-Files: `test/unit/` (new contract test files).
-
-### T4 — Done: https://codeberg.org/guettli/sharedinbox/pulls/32
-
-### T5 🟢 Snapshot / golden tests for key email list states
-The email list has multiple states: loading, empty, normal, selection mode, search active, error banner.
-Add golden tests using `matchesGoldenFile` for each state so visual regressions surface in CI.
-Files: `test/widget/email_list_screen_test.dart`.
-
----
-
-## Group 6: Architecture & Code Quality
-
-### A1 — Done: https://codeberg.org/guettli/sharedinbox/pulls/39
-
-### A2 — Done: https://codeberg.org/guettli/sharedinbox/pulls/33
-
-### A3 — Done: https://codeberg.org/guettli/sharedinbox/pulls/46
-
-### A4 🟡 Replace raw JSON strings in DB with structured encoding
-`fromJson`, `toAddresses`, `ccJson`, `references` are stored as raw JSON strings parsed on every model conversion.
-Create typed value classes with `fromJson`/`toJson` in `core/models/email.dart` and add a `TypeConverter` in the Drift schema so the DB layer owns the serialisation.
-Files: `lib/data/db/database.dart`, `lib/core/models/email.dart`, `lib/data/repositories/email_repository_impl.dart`.
-
-### A5 🟢 Enforce layer boundaries via lint custom rules or barrel imports
-The `ui/` layer directly imports `data/` concrete classes in several screens (e.g. `drift` types leak through).
-Add a custom `analysis_options.yaml` rule or a CI lint step that flags any `ui/` import of `data/` (only `core/` interfaces are allowed from UI).
-Files: `analysis_options.yaml`, CI config.
-
----
-
-## Group 7: Developer Experience
-
-### D1 🔴 CI matrix for macOS and Windows builds
-The CI currently tests Linux and Android. The macOS and Windows targets are "scaffolded" and may have accumulated silent breakage.
-Add `flutter build macos --debug` and `flutter build windows --debug` jobs to the CI workflow with the same failure threshold as Linux.
-Files: `.github/workflows/ci.yml` (or Codeberg equivalent).
-
-### D2 — Done: https://codeberg.org/guettli/sharedinbox/pulls/34
-
-### D3 🟢 Document the sync protocol in a SYNC.md architecture doc
-`DB-SYNC.md` exists but focuses on the DB schema. The IMAP IDLE loop, exponential backoff, pending-change queue, and undo cancel logic are spread across four files with no single reference.
-Write `SYNC.md` that describes the full lifecycle of an email action from UI tap to server confirmation.
-Files: `SYNC.md` (new).
