feat(media): add admin media CRUD preview and storage cleanup

TODO.md

@@ -273,6 +273,7 @@ This file is the single source of truth for roadmap and delivery progress.
 - [2026-02-12] MVP1 media upload pipeline started: admin `/api/media/upload` accepts metadata + file upload with permission checks, stores files via local adapter (`.data/media`), and persists upload metadata to `MediaAsset`.
 - [2026-02-12] Upload storage is now provider-based (`local` + `s3`) via `CMS_MEDIA_STORAGE_PROVIDER`; admin-side GUI toggle remains a later MVP item.
 - [2026-02-12] Media storage keys now use asset-centric layout (`tenant/<id>/asset/<assetId>/<fileRole>/<assetId>__<variant>.<ext>`) with DB-managed media taxonomy.
+- [2026-02-12] Admin media CRUD now includes list-to-detail flow (`/media/:id`) with metadata edit and delete actions.
