fix(i18n): hardkodierte Strings in Cluster/Users/Backups/Alerts bereinigen

- Cluster: statusTag() bekommt t-Parameter; Status-Labels (online/offline/
  joining/leaving/unknown) → cluster.status.* Keys
- Users: 'You'-Tag → t('users.you') / de: 'Ich'
- Backups: 'OK'-Status-Tag → t('backups.okTag')
- Alerts: Kanal-Kind-Labels + alle SMTP-Formular-Labels in t() überführt
- en/de: cluster.status.*, users.you, backups.okTag, alerts.smtp.*,
  alerts.kindWebhook/kindEmail ergänzt
