feat(undo-log): hyperlink email rows in Undo Log Detail (#474) (#547)

## Summary

- Each email row in the **Undo Log Detail** "Emails" section is now tappable.
- Tapping resolves the email via `EmailRepository.findEmailByMessageId(accountId, messageId)` and navigates to its **current** location, so the link survives the move/snooze that changed its IMAP UID.
- If the email has no Message-ID, or no row matches the lookup (e.g. hard-deleted), a SnackBar explains the situation instead of navigating.

A `chevron_right` trailing icon was added to signal the rows are now navigable.

Closes #474

## Test plan

- [x] New widget test `test/widget/undo_log_detail_screen_test.dart` covers:
  - tap on a row whose lookup hits → navigates to `/accounts/<acc>/mailboxes/<encoded>/emails/<encoded>` with the **current** mailbox/id
  - tap when lookup returns `null` → "Email no longer exists" SnackBar, no navigation
  - tap when the original row has no Message-ID → "no Message-ID" SnackBar, no navigation

 ## Issue Label Workflow
 
-We use issues, follow this label state machine:
+Automation is handled by [agentloop](https://github.com/guettli/agentloop) running every 5 minutes via cron. Add a label to trigger an agent:
 
-- **State/Ready** — Issue is available to pick up
-- **State/InProgress** — Set this when you start working on an issue
-- **State/Question** — Set this when you hit a blocker or need clarification
+| Label | Trigger | Outcome |
+|---|---|---|
+| `loop/plan` | Planning agent reads the issue and writes an implementation plan as a comment | Issue moves to `loop/plan-done` |
+| `loop/code` | Coding agent implements the change, creates a branch + PR | Issue routes to `loop/merge` |
+| `loop/merge` | Merge agent rebases, waits for CI, and merges the PR | Issue moves to `loop/merge-done` |
 
-List open issues ready to pick up:
+**State machine:**
 
-```bash
-fgj issue list --json --state open | jq '[.[] | select(.labels[].name == "State/Ready")] | .[] | {number, title, html_url}'
+```
+loop/plan  →  loop/plan-in-process  →  loop/plan-done
+                                     ↘  NeedSupervisor  (on failure)
+
+loop/code  →  loop/code-in-process  →  loop/merge (via route)
+                                     ↘  NeedSupervisor  (on failure)
+
+loop/merge →  loop/merge-in-process →  loop/merge-done
+                                     ↘  NeedSupervisor  (on failure)
 ```
 
-Rules:
+**Rules:**
 
-- Never start work on an issue without `State/Ready`
-- When working via the agent loop: `State/Ready` → `State/InProgress` is set automatically
-  by `agent_loop.py` before the agent starts — do **not** set it yourself.
-- When working manually: switch to `State/InProgress` as your **first action**:
-  ```bash
-  fgj issue edit <NUMBER> --remove-label "State/Ready" --add-label "State/InProgress"
-  ```
-- If blocked, replace current state label with `State/Question` and leave a comment explaining the blocker
-- When done and CI is green, close the issue:
-  ```bash
-  fgj issue close <NUMBER>
-  ```
+- Only issues authored by allowed users are picked up (guettli, guettlibot, guettlibot2, forgejo-actions).
+- An issue with `NeedSupervisor` needs human attention — investigate, fix, then re-label.
+- The merge agent merges the PR automatically once CI is green. A human still reviews the PR before it merges if branch protection requires a review.
+- Planning agents only post a comment — they do NOT write code or open PRs.
+- `loop/*` labels are managed by agentloop — do not set them manually while an agent is active.
+
+**Typical lifecycle for a new feature:**
+
+```
+1. Create issue
+2. Add label loop/plan   → agent writes plan as comment
+3. Review plan, request changes or approve
+4. Add label loop/code   → agent implements + opens PR + hands off to merge
+5. (Optional) Review PR before it merges
+6. Merge agent waits for CI and merges the PR automatically
+```

-# 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`).

-# Snooze Feature Plan
-
-## Goal
-Allow users to snooze emails, moving them to a special folder and bringing them back to the Inbox at a specified time. Snooze data must be stored in the account (IMAP/JMAP) for cross-device synchronization.
-
-## Technical Approach
-
-### 1. Metadata Storage (Account Sync)
-- **Keyword format:** `snz:<ISO8601_TIMESTAMP>` (e.g., `snz:2026-05-10T15:00:00Z`).
-- **JMAP:** Use `keywords`.
-- **IMAP:** Use User Flags (keywords).
-
-### 2. Database Changes
-- **Migration v22:**
-    - `Emails` table:
-        - `snoozedUntil` (DateTime, nullable)
-        - `snoozedFromMailboxPath` (String, nullable) - to remember where to move it back (usually INBOX).
-    - Index on `snoozedUntil`.
-
-### 3. Repository Updates (`EmailRepository`)
-- New method: `Future<void> snoozeEmail(String emailId, DateTime until)`
-    - Optimistically update local DB.
-    - Enqueue `snooze` change.
-- New method: `Future<int> wakeUpEmails(String accountId)`
-    - Find local rows where `snoozedUntil <= now`.
-    - Enqueue `move` back to original mailbox.
-    - Clear snooze metadata.
-
-### 4. Sync Loop Integration
-- In `AccountSyncManager`, call `wakeUpEmails(accountId)` at the start of each sync cycle.
-- Update IMAP/JMAP sync logic to parse `snz:` keywords and update local `snoozedUntil` / `snoozedFromMailboxPath`.
-
-### 5. UI Implementation
-- **Snooze Picker:** A dialog with options like "Later today", "Tomorrow morning", "Next week", "Custom".
-- **Action:** Add "Snooze" icon to `EmailListScreen` selection bar and `EmailDetailScreen`.
-- **Mailbox:** Ensure a "Snoozed" mailbox exists (create if missing).
-
-## Implementation Steps
-1. [ ] Database migration and model updates.
-2. [ ] Repository implementation for `snoozeEmail` and `wakeUpEmails`.
-3. [ ] Update flush logic for IMAP and JMAP to handle `snooze` mutations.
-4. [ ] Update sync logic to parse snooze keywords.
-5. [ ] Integrate `wakeUpEmails` into the sync loop.
-6. [ ] UI: Snooze picker dialog.
-7. [ ] UI: Add Snooze action to list and detail screens.
-8. [ ] Testing and validation.
