feat(settings): server-sync UI aufräumen (#108)

- Login-Status + Logout auf eigene ElevatedCard
- Logout-Button als OutlinedButton (Material-Button statt TextLink)
- Letzte Sync direkt unter Verbindungsstatus ohne Divider
- Refresh-IconButton neben Serverstatus entfernt
- Server-URL Reset nur sichtbar wenn nicht-default Adresse
- Manuelle Sync-Buttons entfernt (vollautomatisch)
