SQLite locking:
- Enable WAL journal mode in init_db (readers don't block writers)
- Set busy_timeout=30000ms in init_db
- Add timeout=30 to every aiosqlite.connect() across db.py, validator.py,
enricher.py, main.py so connections wait up to 30s instead of crashing
Error status:
- 4xx/5xx HTTP responses are now prescreen_status='error' (server alive
but broken/blocking) instead of 'live'
- Added 'error' counter to validator stats and orange Error stat box in UI
- Added ps-error CSS class (orange) and filter option in Browse tab
