feat(advisor): evidence-framed header + bindingness contract seam

Rework the Compliance Advisor header ("Diese Antwort stuetzt sich auf")
to describe the EVIDENCE rather than the documents: binding
Rechtsgrundlagen split from Leitlinien (soft-law guidance), a
per-regulation breakdown, plus Abbildungen, Fussnoten and Evidence Units.
No fabricated trust score — objective counts only.

- bindingness is a canonical Legal-KG fact (APEX rule): added an optional
  EvidenceUnit.bindingness contract seam; the FE renders the split from it
  and degrades to a neutral per-regulation breakdown when it is absent
  (SDK/RAG asked via board to populate it in /retrieve).
- evidence-grouping.ts: pure, tested grouping/counting model.
- route.ts: optional `audience` field (tonality) kept out of the retrieval
  question; answers lead with a "Kurz gesagt" summary, structured by theme.
- E2E + unit tests updated for the evidence framing.

Not deployed.
