fix: improve UI refresh timing after force-stop recovery

- Increase recovery delay from 1s to 3s (force-stop recovery can take time)
- Add immediate refresh + delayed refresh to catch recovery at different stages
- Better error handling for database not ready yet (shows 'Checking...' instead of error)
- Add logging to indicate when config not found is normal (after uninstall/reinstall)

Previously, after force-stop recovery:
- Configuration check happened too early (1s delay not enough)
- UI showed error immediately if database not ready
- Single refresh might miss recovery completion

The fix:
- Immediate refresh when app becomes visible (catches fast recovery)
- Delayed refresh after 3 seconds (catches slower recovery)
- Better error messages indicating database might not be ready yet
- Note that config not found is normal after uninstall/reinstall (database wiped)

This ensures UI properly refreshes configuration status and notification info
after force-stop recovery completes.
