Notiz-Medien & Sprachnachrichten: Fotos/Videos/Dateien + Audio an Notizen

Wiederverwendbarer UI.noteMediaAttacher für beide Notiz-Stellen (UI.noteModal
+ Notizblock-Seite). note_media-Tabelle + POST/DELETE /api/notes/{id}/media
(vor der gierigen /{parent_type}/{parent_id}-Route). Audio per MediaRecorder,
serverseitig nach m4a/AAC transkodiert (ffmpeg) — iOS spielt Chrome-Opus-webm
nicht ab. UI.lightbox global eingeführt. Mikrofon-Policy microphone=(self) +
CSP media-src 'self' blob:, Datenschutz v6. Disk-Cleanup für note_media bei
Notiz-, Account- und Admin-User-Delete. Reine Medien-Notiz ohne Text erlaubt.
noteModal-Bug gefixt: notes.get() liefert Array -> existing[0] statt
existing?.id (verhinderte Bearbeiten, erzeugte Duplikate). 12 neue Tests.

admin.py enthält außerdem KI-Vision-Statusfelder aus paralleler Arbeit
(nicht sauber trennbar ohne interaktives Staging).
