- Fix seed data to match actual DB schemas (capture.processed, daily_focus.completed, weblinks junction table)
- Add date/datetime coercion in BaseRepository for asyncpg compatibility
- Add UUID validation in BaseRepository.get() to prevent DataError on invalid UUIDs
- Fix focus.py and time_tracking.py date string handling for asyncpg
- Fix test ordering (action before delete) and skip destructive admin actions
- Fix form_factory FK resolution for flat UUID strings
- Fix route_report.py to use get_route_registry(app)
- Add asyncio_default_test_loop_scope=session to pytest.ini
