feat(advisor): Case Workspace v2 — Evidence grouping, human names, 3-column, summary

Reworks the advisor toward a Compliance Case Workspace (review feedback):
- Rename user-facing "Quellen" -> "Evidence".
- Evidence grouped by document/regulation family (count + expandable) — no more
  unsorted DSK/DSK/DPF/... jumble.
- Human-readable regulation names via a display registry (DSK Sdm B51 -> "DSK
  Standard-Datenschutzmodell (SDM)" / Kapitel B51); generic, bridges G2.
- Evidence summary "Antwort basiert auf" with meaningful counts; Regelwerke = distinct
  FAMILIES (fixes the inflated count). NO fabricated trust score (needs a defined basis).
- Expanded mode = 3-column workspace (question+summary | answer | evidence, independent
  scroll) + history switcher; narrow mode stays stacked.
- Prompt: push aggressive markdown structure (## per aspect, numbered phases).

Deferred/coordinated on board: C8 diagrams (RAG contract), answer<->evidence coupling
[1] (needs LLM citation anchors — phase 2), G1 retrieval relevance + G2 metadata (RAG).
tsc clean, 17 vitest, check-loc 0.
