## 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) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Thomas SharedInbox <sharedinbox@thomas-guettler.de> Reviewed-on: https://codeberg.org/guettli/sharedinbox/pulls/378
