feat(web): wire RowActionsMenu in requests + quarantine

Requests: primary Approve, secondary [Override, Reject].
Quarantine: primary Resolve, secondary [Play, Delete file]; the
Delete-via-Lidarr conditional stays inline above md (preserves the
disabled-with-tooltip semantics) and hides below md to avoid
crowding — the operator can still trigger it from the desktop view.
