Backend: Medien-Typen, Sprachnotizen, Event-Felder und Sync-Härtung

- Event-Medien tragen Typ (image/video/audio), Dauer und Notiz; Videos
  bekommen ein Poster, Audio wird per ffmpeg nach AAC (audio/mp4)
  gewandelt, Originale werden mit Range-Unterstützung gestreamt.
- Upload nimmt eine Notiz (caption) direkt mit, PATCH ändert sie später.
- Neue Event-Felder: Zeitraum (end_date), Kategorie, Personen, Meilenstein.
  Regeln zentral in EventFields, damit CRUD und Sync gleich prüfen.
- Titel darf leer sein: ein Event entsteht mit dem ersten Eintrag.
- Artisan-Befehl media:transcode-voice-notes wandelt alte WebM/Ogg-Notizen,
  die Safari nicht abspielen kann.
- Login-Throttling, Settings-Validierung, Sync-Fehlercodes ohne Rohtext.
