Use-Case-Mapping-Filter für Master Controls + Mapper-Präzisionsfix

Phase 2: Live-Filter an /sdk/master-controls (Use Case, Quell-Regulierung,
Verifikations-Methode, Coverage, Primärzweck-Toggle, category via Member-EXISTS).
API mit EXISTS-Filtern + gecachten Meta-Counts in master-controls/route.ts.

Phase A: neue UseCase telekommunikation + Fix der Impressum-Fehlrouten im
Register (TKG/AT-TKG->telekommunikation, telemedien->dse, GewO->handelsrecht);
echte Impressum-Quellen (TMG/Mediengesetz) bleiben impressum. Deterministischer
Seed aus source_regulation; Tests grün.
