Fix: Update-Check via mailwolt-fetch-tags + Fehlerdetails in Settings-Toast

- Neu: scripts/mailwolt-fetch-tags ruft git ls-remote als App-User auf (hat Credentials),
  schreibt neuesten Tag nach /var/lib/mailwolt/version_remote
- CheckUpdates.php nutzt jetzt sudo mailwolt-fetch-tags statt direktem git fetch als www-data
  (www-data hat keine Git-Credentials für private Repos)
- SettingsForm.php zeigt tatsächliche Fehlerzeilen ([!], error, failed) im Toast statt
  generischer "fehlgeschlagen"-Meldung
- installer.sh + update.sh installieren mailwolt-fetch-tags nach /usr/local/sbin/
- update.sh trägt mailwolt-fetch-tags automatisch in sudoers nach (Upgrade-Pfad)
