Phase 5: Projekt-/Media-/Plugin-API im Control Core (§23.1, §13.3)

- Projekte: CRUD + Activate (State-Store-Revision), §23.1/§24.2
- Medien: Import mit Duplikaterkennung (§13.3), Liste mit
  Missing-Markierung (§13.2)
- Plugins: Listing nach Lifecycle-Status gruppiert (§14.5),
  Enable mit Lifecycle-Advancement, 404 bei unbekanntem Plugin
- Art-Net-Status-Endpunkt (§23.1)
- Diagnostics erweitert um State-/Projekt-Revisionen (§28.2)
- Commands schreiben jetzt auch in den State-Store (§6.4)
- SQLite check_same_thread=False für FastAPI async handlers
- python-multipart für UploadFile hinzugefügt
- Discovery-Fix: Builtin-Plugins nach Kategorie-Unterverzeichnissen
  (generators/, filters/) durchsuchen statt nur Direktkinder
- 8 neue Integrationstests: Projekt-CRUD-Roundtrip, Activate,
  Media-Import mit Duplikat, Plugin-Listing (10+14 verifiziert),
  Enable-404, Diagnostics-Revisionen
- Gesamtsuite 557 grün, Ruff grün
