- GET /alerts gains tri-state acked + read query params
- new endpoints: DELETE /{id} (soft-delete), POST /bulk-delete, POST /bulk-ack, POST /{id}/restore
- requireLiveInstance 404s on soft-deleted rows; restore() reads the row regardless
- BulkReadRequest → BulkIdsRequest (shared body for bulk read/ack/delete)
- AlertDto gains readAt; deletedAt stays off the wire
- InAppInboxQuery.listInbox threads acked/read through to the repo (7-arg, no more null placeholders)
- SecurityConfig: new matchers for bulk-ack (VIEWER+), DELETE/bulk-delete/restore (OPERATOR+)
- AlertControllerIT: persistence assertions on /read + /bulk-read; full coverage for new endpoints
- InAppInboxQueryTest: updated to 7-arg listInbox signature
