When zone errors bubble up through Dart's async machinery the stack
trace is in package:stack_trace chain format (with '===== asynchronous
gap =====' separators). Flutter's StackFrame parser asserts on those
lines. FlutterError.demangleStackTrace strips the chain format back to
a plain VM trace before Flutter tries to parse it.

runZonedGuarded's error handler runs in the parent zone, so calling
runApp there caused a Flutter zone mismatch with ensureInitialized.
Removed the async keyword from main (redundant with runZonedGuarded)
and replaced the zone error handler's runApp call with reportError.

## Summary
Fixes the crash reported in #397: `Scaffold.of() called with a context that does not contain a Scaffold.`
- `Scaffold.of(context)` was called in the `onPressed` of the bottom-nav menu `IconButton` using the widget's own `build` context. That context is the *parent* of the `Scaffold` being returned, so Flutter correctly throws.
- Fix: wrap the `IconButton` in a `Builder`, which provides a child `ctx` that is a proper descendant of the `Scaffold`. `Scaffold.of(ctx)` then resolves correctly.
## Test plan
- [ ] Run app with bottom menu position enabled, tap the hamburger icon — drawer opens without crashing.
- [ ] Run app with top menu position — no regression (bottom nav is not rendered).

## Summary
- Removes the `AlertDialog` popup that appeared when tapping delete in thread view
- Deletion now happens immediately, matching the behaviour of the single mail view
- The existing `UndoShell` widget already listens for new `UndoAction` pushes and shows a snack bar with an **Undo** button — no extra UI code needed
Closes#398

## Summary
- When deleting a mail from the single Mail View, \`pushAction()\` was called with \`unawaited\` before \`_navigateTo()\`. This meant the UndoShell snack bar fired *after* navigation had already started, showing the snack bar on the destination scaffold mid-transition — which prevented the snack bar's duration timer from starting correctly.
- Fixed by changing \`unawaited(pushAction(...))\` to \`await pushAction(...)\`. Since Riverpod fires \`ref.listen\` synchronously when state changes, the UndoShell now queues the snack bar on the current stable scaffold *before* \`_navigateTo()\` is called. The snack bar then naturally transfers to the destination scaffold and auto-dismisses after 5 seconds as intended.
Closes#399
## Test plan
- [x] All 338 unit/widget tests pass
- [ ] Manually delete a mail from single Mail View and verify the snack bar appears and auto-dismisses after ~5 seconds
- [ ] Verify the Undo button in the snack bar still works

Closes#373
## Summary
- **Schema v38**: two new columns on `user_preferences` — `prefetch_mode` (default `wifiOnly`) and `body_cache_limit_mb` (default 100 MB).
- **`BodyCacheService`**: queries for emails that have no cached body, fetches them newest-first in batches of 20, and evicts the oldest cached bodies when the configured size limit is exceeded.
- **Separate WorkManager task** (`si_bg_prefetch`): runs hourly with `NetworkType.unmetered` (Wi-Fi) or `NetworkType.connected` (any) depending on the user's choice. The task is cancelled when prefetch is disabled.
- **App startup**: reads the stored preference from the DB and re-registers the WorkManager task with the correct constraint.
- **Preferences screen**: radio group for prefetch mode (Wi-Fi only / Any network / Disabled) and a dropdown for cache size limit (50 / 100 / 200 / 500 MB).
## What is NOT downloaded
Binary attachments are never fetched — `getEmailBody()` stores only `textBody` and `htmlBody`. The cache size limit + per-run batch cap (20 emails) keep storage bounded even on large mailboxes.
## Test plan
- [x] `task analyze` — no issues
- [x] `task test` — all 492 tests pass (incl. updated migration_test.dart for v38)

## Summary
- When viewing an email and then deleting (or archiving/moving/snoozing) it, the app navigates to the next email in the thread list.
- `getEmailBody` fetches from the network on a cache miss, causing the hourglass / loading spinner the issue describes.
- `EmailDetailNotifier` now fires a background `getEmailBody` call for the next thread's `latestEmailId` as soon as the current email finishes loading.
- `getEmailBody` already caches results in the `EmailBodies` table with a 7-day TTL, so by the time the user triggers a navigation action the body is pre-warmed and renders instantly.
## What changed
`lib/di.dart` — `EmailDetailNotifier.build()` calls `_prefetchNextEmailBody` (fire-and-forget via `unawaited`) after loading the current email. The helper respects the `afterMailViewAction` user preference: if set to `showMailbox` it does nothing.
## Test plan
- [ ] Open an email, delete it — next email should appear without the spinner
- [ ] Verify the same for archive, move, and snooze actions
- [ ] Verify behaviour is unchanged when `afterMailViewAction` is set to `showMailbox`
- [ ] Verify the last email in the list still pops back to the mailbox list correctly

## Summary
Closes#377
- Adds a new `ImageTrustedSenders` Drift table (schema v37) that stores email addresses for which remote images are loaded automatically (per device, not per account)
- When the user taps "Load remote images", the sender's address is saved and a 3-second snackbar appears with a "Settings" hyperlink to undo the choice in preferences
- Both `EmailDetailScreen` and `ThreadDetailScreen` check the trusted senders list on open and auto-load images for known senders
- The Preferences screen gains a new "Trusted image senders" section listing all saved senders with individual remove buttons
## Test plan
- [x] `dart run build_runner build` regenerates `database.g.dart` cleanly (schema v37)
- [x] `flutter analyze` — no issues
- [x] Migration test updated: checks `image_trusted_senders` table exists after upgrade and fresh install
- [x] `FakeUserPreferencesRepository` updated with three new interface methods
- [x] All 490 unit + widget tests pass (1 pre-existing golden test failure unrelated to this change)

## What changed
`searchAddresses` (used by the To/Cc/Bcc autocomplete) now runs two passes over the candidate email rows:
1. **Sent-folder rows first** — the mailboxes table is queried for mailboxes with `role='sent'`; any email row whose `mailboxPath` matches gets processed before inbox/other rows. Within this group addresses are ordered by `receivedAt` DESC as before.
2. **All other rows** — processed after sent rows, also by `receivedAt` DESC.
Within sent-folder rows, `toAddresses` and `ccJson` are checked before `fromJson` (the sender in a sent email is our own address, not a useful suggestion). For non-sent rows the original order (`fromJson`, `toAddresses`, `ccJson`) is kept.
This means: if you wrote to `info@foo.de` yesterday and received spam from `info@spam.de` today, typing "i" surfaces `info@foo.de` first.
## How verified
- All 492 unit tests pass (`task test`).
- Added a dedicated test `searchAddresses prioritises sent-folder addresses over newer received` that inserts an older sent email and a newer received email matching the same query prefix and asserts the sent-folder address is returned first.

Closes#372
## What changed
- **New widget** `lib/ui/widgets/email_headers_dialog.dart`: full-screen header browser that organises headers into collapsible groups:
- **Headers** — all standard headers (expanded by default)
- **List- Headers** — all `List-*` headers grouped together (expanded)
- **Received** — all `Received` headers, **collapsed by default**; shows the inter-hop duration between consecutive entries and highlights delays in colour (green < 30 s, orange < 5 min, red >= 5 min)
- **ARC- Headers** — all `ARC-*` headers (above X-, expanded)
- **X-Prefix Headers** — X- headers split by their second component (e.g. `X-Google-*` → "X-Google Headers"), sorted alphabetically, at the very bottom
- **`email_detail_screen.dart`**: `_showHeaders` now uses `EmailHeadersDialog`; `_showStructure` converted from `AlertDialog` to `Dialog.fullscreen()` — satisfying "Make popup windows full screen."
- **`scripts/check_coverage.dart`**: new widget file added to the `_excluded` set (UI widgets are covered by integration tests, not unit tests).
## Verified
`task check` passes (analyze: no issues, 491 unit tests pass, coverage >= 80 %).

During _load(), check whether a password exists in secure storage and track the result
in _hasStoredPassword. The password field validator now requires user input when no
password is stored, so _tryConnection() fails fast at form validation instead of
throwing an unhandled StateError.
