Merge remote-tracking branch 'origin/main' into test-foo

## Summary

- Downgrades `.fvmrc` from Flutter `3.44.1` back to `3.44.0` — `ghcr.io/cirruslabs/flutter:3.44.1` does not exist on GHCR so every Dagger-based deploy job fails with "not found"
- Extends `scripts/check_ci_images.sh` to also validate the Flutter image derived from `.fvmrc` (previously only literal `From("...")` calls in `ci/main.go` were checked, so Renovate bumps to non-existent images went undetected)
- Updates `.pre-commit-config.yaml` to trigger the `ci-image-exists` hook on `.fvmrc` changes as well as `ci/main.go`

## Root cause

Recent run logs showed:
```
! ghcr.io/cirruslabs/flutter:3.44.1: not found
Error: failed to resolve image "ghcr.io/cirruslabs/flutter:3.44.1"
```
Renovate bumped Flutter to 3.44.1 (#411) but cirruslabs has not published that image — the latest available is `3.44.0`. Same root cause as #409, but the pre-commit guard only watched `ci/main.go`, not `.fvmrc`.

Closes #427

-# 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`).

-# Plan Log
-
-## 2026-05-10
-- Improved Undo Log (Issue #7): Added support for undoing any action from history.
-- Refactored `UndoService.undo()` to support targeted rollbacks by action ID.
-- Removed "latest only" restriction from `UndoLogScreen`.
-- Successfully deployed release APK to distribution server via `task deploy-android`.
-- Verified system integrity with unit, widget, and E2E integration tests.
-
-## 2026-05-10
-- Implemented global Undo Log with persistent history.
-- Refactored `UndoService` to store a list of recent actions instead of just the latest one.
-- Added `UndoLogScreen` to view and interact with undo history.
-- Added "History" icon to account list for better discoverability.
-- Updated `.gitignore` to better handle Dart/Flutter and Android tool artifacts.
-- Verified all changes with fast check suite (analyze + unit + widget tests).
-
-## 2026-05-09
-- Fixed Crash Page (Issue 3): Added Codeberg reporting button.
-- Fixed Show Mail Headers (Issue 1): Added raw header storage and UI display.
-- Fixed Exception on Undo of delete (Issue 2): Added serialization to EmailAddress.
-- Updated Taskfile with Nix experimental features check.
-- Pushed all changes to branch `fix-issues`.
-
-## 2026-05-09
-- Fixed Undo feature for IMAP accounts.
-- Identified that IMAP moveEmail hard-deletes local rows, making Undo impossible without data.
-- Added `originalEmails` to `UndoAction` and `restoreEmails` to `EmailRepository`.
-- Updated UI to fetch email data before move/delete to support restoration.
-- Fixed `UndoService` to restore rows and be more robust with pending change cancellation.
-- Verified with `test/unit/undo_reproduction_test.dart` and updated unit tests.
-- Successfully deployed to Android.
-
-## 2026-05-09
-- Implemented Network Resilience (Task 1/4 from next.md).
-- Added exponential backoff logic (5s to 15m) to IMAP and JMAP sync loops.
-- Added permanent error detection (auth/credentials) to stop sync loops gracefully.
-- Improved "Pull to Refresh" in email list to trigger full account sync and bypass backoff.
-- Verified with integration tests.
-
-- Started work on Sync Reliability (Task 1/5 from next.md).
-- Added `verifySyncReliability` to `EmailRepository` interface and models.
-- Implemented `verifySyncReliability` in `EmailRepositoryImpl` for IMAP and JMAP.
-- Added `SyncHealth` table to database (Schema v19).
-- Created `ReliabilityRunner` for periodic verification.
-- Integrated sync health indicators in `AccountListScreen` UI.
-- Added manual "Verify sync health" action.
-- Verified with new integration tests in `test/integration/sync_reliability_test.dart`.
-- All integration tests (IMAP and JMAP) passing.
-- Fixed several compilation and analysis issues.
