feat(docs-center): report reading section (type=report) on /api/cma/docs

Increment #2 over PoC ede0524 (task yanxue-20260924-cma-report-source).

- backend derives reports from existing drop points (wisdom/_reports + every profile pending-tasks/_reports), read live per request, no cache, no rebuild

- gate = front-matter plus non-empty conclusion; missing either means silently out of the list (receipts/audits never enter); title/date/domain/sources missing are marked incomplete instead of rejected

- entity + role partitioning (ceo/it cross-entity; others own entity plus group/generic); kpi_refs resolve to a one-hop metric link

- new GET /api/cma/docs/report/{rid} detail endpoint; knowledge branch unchanged (type defaults to knowledge)

- frontend: CMAKnowledge adds a report reading pane (filters + detail dialog), reuses the existing markdown renderer, no new deps

(cherry picked from commit 7c6e0857e68133f5ba2a539fd3569aeb82547911)
