feat(triage): Ticket-Fixes (Daten + Code) + prod-fähige Triage

Daten-Fixes (conflict-decisions.json, re-ingest-stabil) für ~30 Tickets:
Merges (Jamie/Hiro/Mino/Jana/Blacky/Sakura/Malou/Socke→Marty), Eltern-Korrekturen
(Jacky/Idefix/Ichika/Roni/Ethan), Kruke→Kuke (+ Todesdatum), Targa-Wurf R14 + Druna,
Stacy/Merle/Domi/Eliza; Joghurt-Phantomwurf entfernt.

Code-Fixes:
- Gaida & alle Verstorbenen: Status wird aus Todesdatum/Abgabe abgeleitet
  (Program.cs Startup-Sweep heilt Altfälle; IngestResolved re-derived nach Freeze).
- CoCo: Scheckungsart wird bei jeder Schecke angezeigt (Platzhalter wenn leer).
- M-Wurf/Gale: über-gemergte Fremdtiere via neuem litterChildren-Override entfernt.
- renameTo eltern-verknüpfungssicher (Quell-Name im Index); dateOfDeath als Override.

Prod-fähige Triage (API):
- GET /feedback/{id} + GET /feedback?status= (kein 2-MB-Dump).
- POST /import/ingest-resolved/upload (multipart) → Ingest gegen Prod ohne SSH.

Tests: 280 Backend, 149 Frontend, alle Python, betroffene Playwright grün.
