docs(adr): correct stale statuses for shipped ADRs

Audit of all ADR status fields found several marked Proposed/Draft that are in
fact implemented. Correct them with an evidence pointer; also fix the ADR-025
title that read "ADR-024".

- ADR-007 background vector sync: Proposed -> Accepted/implemented
- ADR-008 MCP sampling: Proposed -> Accepted/implemented
- ADR-009 semantic.read scope: Proposed -> Accepted/implemented
- ADR-010 webhook-based vector sync: Proposed -> Accepted/implemented
- ADR-012 unified multi-algorithm search: Proposed -> Accepted/implemented
- ADR-013 RAG evaluation: Proposed -> Partially implemented
- ADR-018 Nextcloud settings-UI app: Proposed -> Accepted/implemented
- ADR-025 dynaconf: Proposed -> Accepted/implemented; fix title typo (ADR-024 -> ADR-025)
