feat: add real-time HTTPS status detection on admin config page

- Detect actual HTTPS status from current request (scheme + X-Forwarded-Proto)
- Auto-sync database when HTTPS status mismatch is detected
- Show real-time connection info (protocol, host, port)
- Display helpful message when accessing via HTTPS but config shows disabled
- Add CSS styling for detection status display
- Users now see accurate HTTPS status even if database wasn't in sync
