test(handlers): add HTTP handler tests for GetA2AQueueStatus and PatchAbilities

GetA2AQueueStatus (9 cases):
- queue_id empty → 400 (via gin.CreateTestContext to bypass router)
- no identity, no org token → 404 (existence-non-inference policy)
- org token set → skips caller workspace check (authorized)
- caller workspace matches caller_id → 200
- caller workspace matches workspace_id → 200
- queue not found (sql.ErrNoRows) → 404
- queue auth-fields DB error → 500
- wrong caller workspace → 404 (IDOR collapsed to 404)
- status fetch DB error → 500
- full happy path → 200 with JSON body

PatchAbilities (11 cases):
- invalid workspace ID → 400
- invalid request body → 400
- no ability fields → 400
- workspace not found (ErrNoRows) → 404
- workspace not found (exists=false) → 404
- update broadcast_enabled=true → 200
- update talk_to_user_enabled=false → 200
- update both abilities → 200
- broadcast_enabled DB error → 500
- talk_to_user_enabled DB error → 500
