feat: linting + format automation + IMAP integration tests against Stalwart

- Add `format` task (fvm dart format .) and pre-commit dart-format hook
- Fix pre-commit task-check hook to use nix develop --command task
- Add CI format-check step (dart format --set-exit-if-changed .)
- Enable directives_ordering, curly_braces_in_flow_control_structures,
  discarded_futures, unnecessary_await_in_return, require_trailing_commas
- Apply 330 trailing-comma fixes (dart fix --apply) across all files
- Wrap intentional fire-and-forget futures with unawaited() to satisfy
  discarded_futures lint in account_sync_manager, email_repository_impl,
  and UI screens
- Add test/integration/email_repository_imap_test.dart: 8 tests against
  real Stalwart (sync, body fetch+cache, send, search, flag/move/delete)
- Remove 14 fake-IMAP unit tests migrated to Stalwart integration tests
- Fix flushPendingChanges move test: create Trash folder before IMAP MOVE
- Lower coverage gate 85%→80%: IMAP paths now tested by Stalwart (real),
  not counted in unit-test lcov
- Delete LINTING.md (plan fully executed)
