feat: background device status check every 240s instead of on page load

Browse Source 
- Add online, leds, version, last_check columns to wled_devices table
- Background job checks all WLED devices every 4 minutes
- Initial check on startup
- Devices page reads status from DB (instant page load)
- 'Alle jetzt pruefen' button triggers manual check
