feat: Control-Detail Provenance + Atomare Controls Seite

Backend: provenance endpoint (obligations, doc refs, merged duplicates,
regulations summary) + atomic-stats aggregation endpoint.
Frontend: ControlDetail mit Provenance-Sektionen, klickbare Navigation,
neue /sdk/atomic-controls Seite mit Stats-Bar und gefilterer Liste.
