User Panel: Phase-8-Abschluss, Titelbild/Lizenzen/Zeitzonen und KI-Pruef-Pipeline

Phase 8 (Rest) + Umbauten vom 10./11.06.:
- Ein Titelbild pro PM (Cover 1280x580), SVG-Platzhalter-Set + Picker,
  PressReleaseCoverImage-Resolver
- Lizenz-/Rechteformular nach "Lizenztyp Bildupload" (7 Lizenztypen,
  Personen-/Sachrechte-Status, bedingte Pflichtfelder, Risikohinweise)
- Veroeffentlichungs-Box vereinfacht (Embargo aus der Form-UI entfernt),
  geplante Termine in Europe/Berlin (Speicherung UTC, DISPLAY_TIMEZONE)
- Quota-Stub (users.press_release_quota) + monatlicher Reset-Command
- Einreichungs-Modal einheitlich in Show/Create/Edit; Ghost-Buttons auf
  filled; PM-Editor-Layout responsive entkoppelt (.pr-editor-layout)

KI-Pruef-Pipeline (Phasen 1-5 des Entwicklungsplans):
- API-Haertung: status nicht mehr per API setzbar, eigene Submit-Route
  durch denselben Funnel (Blacklist, Quota, Status-Log)
- Klassifikation Rot/Gelb/Gruen asynchron (Queue classification,
  OpenAI-Treiber + deterministischer Fallback), ki_audits-Audit-Log
- Routing: Rot -> rejected + Mail, Gelb -> Review-Queue, Gruen ->
  Auto-Publish; Scheduler publiziert nur gruene faellige PMs
- Content-Score 0-100 -> Stufe (Standard/Geprueft/Hochwertig) inkl.
  Editor-Panel und Badges; Re-Klassifikation/-Score bei Aenderung
- Admin: KI-Badge + Filter, On-Demand-Pruefung mit Anbieter-Override

Suite: 442 passed, 4 skipped.
