Introduce a headless `flutter test` suite (83 tests) covering models, utilities, every API endpoint, and the five screens, with shared helpers and fixtures so new tests stay terse. API endpoint methods are statically-dispatched extensions on the BackendAPI singleton, so they cannot be mocked via `implements`. Mock at the Dio HTTP-adapter layer (http_mock_adapter) instead, enabled by two small @visibleForTesting seams: BackendAPI.dioForTesting swaps the singleton's Dio, and BackendReachability.forceOnlineForTesting() forces a deterministic online state so polling widgets load. Add frontend/run_tests.sh and document it in CLAUDE.md. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
