feat: Kontextabhängige Karten-Kategorien

4 feste Farbstufen (primary/secondary/tertiary/mentioned) mit
variablen Labels pro Lage, die von Haiku generiert werden.

- DB: category_labels Spalte in incidents, alte Kategorien migriert
  (target->primary, response/retaliation->secondary, actor->tertiary)
- Geoparsing: generate_category_labels() + neuer Prompt mit neuen Keys
- QC: Kategorieprüfung auf neue Keys umgestellt
- Orchestrator: Tuple-Rückgabe + Labels in DB speichern
- API: category_labels im Locations- und Lagebild-Response
- Frontend: Dynamische Legende aus API-Labels mit Fallback-Defaults
- Migrationsskript für bestehende Lagen
