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
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)

On some Android devices (e.g. Android S1RXS32.50-13-25) the WorkManager
platform channel fails to connect at startup, throwing
PlatformException(channel-error, ...). registerBackgroundSync() now catches
PlatformException and MissingPluginException (plus any other unexpected
failure) and silently disables background sync rather than crashing the app.
Test added: test/unit/background_sync_test.dart verifies the function
completes without throwing in the unit-test environment (where the native
plugin is absent).

Two fixes:
1. notification_service.dart: initNotifications() now catches
MissingPluginException (and any other init failure) so the app no
longer crashes when flutter_local_notifications is unavailable on
some Android devices. _initialized tracks success; showNewMailNotification
skips the plugin call when it never initialised.
2. crash_screen.dart: "Report Issue on Codeberg" no longer puts the full
report in the URL query string. Long stack traces exceeded browser
URL-length limits and caused "create issue failed". The URL now
carries only the pre-filled title; the user copies the full report
via "Copy to Clipboard" and pastes it in the issue body.
Tests added:
- test/unit/notification_service_test.dart: verifies initNotifications()
completes without throwing when the plugin channel is unavailable.
- test/widget/crash_screen_test.dart: verifies the Codeberg URL contains
the title but no &body= parameter.

- Add LocalSieveApplied table (schema v32) keyed by (accountId, messageId)
so each email is processed by Sieve at most once, even across restarts.
- Implement EmailRepository.applySieveRules(): loads the active local Sieve
script, runs the interpreter against new INBOX emails, and queues pending
move/delete/flag_seen changes for any matched rules.
- Wire applySieveRules() into both _AccountSync._sync() and
_JmapAccountSync._sync() after the per-mailbox email sync loop.
- Make _flushPendingChangesImap() treat NONEXISTENT / not-found errors as
silent no-ops (counts as flushed) so a second device racing on the same
email does not accumulate retries.
- Add migration test assertions and a dedicated unit test suite covering
rule matching, deduplication, discard, and multi-email processing.

unawaited saveAction/deleteAction calls in pushAction could outlive the
test and access the SQLite connection after tearDown closed it, causing
the native FFI layer to hit freed memory (SIGBUS / exit code -7).
Making both DB calls awaited ensures pushAction only returns once the
action is fully persisted, eliminating the race condition.

Implements a three-phase Sieve email filtering pipeline:
- Data models (SieveCondition, SieveAction, SieveRule) as sealed Dart classes
- SieveParser: converts RFC 5228 Sieve scripts to a flat SieveRule list,
supporting if/elsif/else, allof/anyof, header/size/exists tests, and all
common actions (fileinto, keep, discard, flag, mark)
- SieveInterpreter: evaluates compiled rules against a SieveEmailContext,
tracking routing state in SieveExecutionContext with implicit keep behaviour
- 40 unit tests covering parser correctness and interpreter execution

Replace the insecure plaintext QR export/import flow with an
end-to-end-encrypted account-transfer mechanism:
- Receiver generates an ephemeral X25519 key pair (20-minute lifetime,
stored in the new share_keys DB table at schema v31) and displays it
as a QR code (sharedinbox.de:pubkey:v1:…).
- Sender scans the public-key QR, selects accounts (or auto-selects
when only one exists), encrypts them with ECIES (X25519-ECDH +
HKDF-SHA256 + AES-256-GCM) and displays an encrypted QR
(sharedinbox.de:encrypted-accounts:v1:…).
- Receiver scans the encrypted QR, decrypts, verifies the 20-minute
expiry and MAC authentication tag, then imports the accounts.
New screens: AccountReceiveScreen (/accounts/receive) and
AccountSendScreen (/accounts/send), accessible from the account-list
drawer and per-account popup menu respectively.
Remove the old insecure AccountExportScreen and AccountImportScreen.

Track how long each mailbox takes to sync and display it in the
sync log expanded view (e.g. "2 new · 5 up-to-date · 1.3s").
- Add optional `duration` field to `MailboxSyncStats`
- Capture per-mailbox start/end time in both IMAP and JMAP sync loops
- Store as `duration_ms` in `sync_log_mailboxes` (schema v30 migration)
- Read back and reconstruct `Duration` in repository
- Show timing alongside fetch/skip counts in per-mailbox breakdown
- Extract `_fmtDuration` helper, reuse for the existing total duration

checkNow() previously delegated to _runAll(), which gated each
account on the _running flag (only true after start() is called).
This meant the manual "Verify sync health" action silently did nothing
if start() had not yet been called, or in any context where the
periodic runner was not active (e.g. widget tests).
Fix: checkNow() now iterates accounts directly and calls
_runForAccount() with force:true, bypassing the _running guard.
The guard is still respected during periodic runs for graceful
shutdown.
Adds three unit tests that reproduce the bug and verify the fix.

Adds a MimePart tree model, parses it from the IMAP BODYSTRUCTURE
when fetching the email body, caches it in a new mime_tree_json column
(schema v28), and exposes a 'Show Mail Structure' overflow menu item
that renders the indented tree (content-type, filename, size, encoding)
in an AlertDialog alongside the existing headers dialog.

Emails with multipart/related structure reference embedded images via
cid: URIs. The WebView's CSP only allows data:/blob: sources, so those
images were never shown. injectInlineImages() now replaces each cid:
reference with a data: URI using the decoded bytes from the MIME tree,
both for double-quoted and single-quoted src attributes.

Two fixes for the UndoLog:
1. Don't delete the original undo log entry when undo is performed.
The entry stays in the log alongside the new inverse action, so
the user can retry the undo if it was silently reverted by an
IMAP sync.
2. Fix IMAP UID mismatch: after an IMAP move is applied on the server
the email gets a new UID in the destination folder. The undo service
now looks up the email by its RFC 2822 Message-ID when the original
row is gone, so the reverse-move pending change carries the correct
UID and actually succeeds on the server.
Add findEmailByMessageId to EmailRepository interface and impl.
Add a regression test that simulates the UID change scenario.

Instead of reconstructing the message from the local DB, fetch the
original bytes live from IMAP (BODY.PEEK[]) or JMAP (Email/get blobId
→ downloadBlob) so the view shows the true unmodified message.

When focus leaves the To field while the address DB query is in flight,
the optionsBuilder Future completes AFTER RawAutocomplete has already
called hide() on the overlay. The completion triggers a second hide()
call, hitting the _zOrderIndex != null assertion in overlay.dart.
Fix: check focusNode.hasFocus after the await; return [] if focus left,
which prevents RawAutocomplete from calling show()/hide() on a closed
overlay.
Also fixes#81 partially: after undo(), push an inverse UndoAction so
the undo log retains a record and the user can re-apply the operation.
Fixes#79

Future.any([Future.delayed(N), stopSignal.future]) left unfired Timers
alive after stop() fired the signal — pending Timers kept the Dart event
loop running and prevented the process from exiting, causing the E2E
integration test to time out (exit 124) instead of exiting cleanly.
Replace all four occurrences with an explicit Timer that completes the
stop-signal and is cancelled in a finally block, so the Dart isolate can
exit as soon as the sync loops are stopped.

Adds RawAutocomplete<EmailAddress> to the To and Cc fields in the
compose screen. As the user types (minimum 2 chars), suggestions are
fetched from the local DB by searching from/to/cc columns of cached
emails. Selecting a suggestion appends it to any existing addresses
already in the field (comma-separated).
New repository method searchAddresses() returns deduplicated
EmailAddress objects matching the query string.
