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

+#   2. PATCH /workspaces/:id/abilities { talk_to_user_enabled: false } disables
+#      delivery: /notify → 403 with error="talk_to_user_disabled" + delegate hint.
+#   3. Re-enabling talk_to_user_enabled restores delivery.
+#   4. broadcast_enabled (default false) — POST /broadcast → 403 when disabled.
+#   5. PATCH { broadcast_enabled: true } enables fan-out.
+#   6. POST /broadcast delivers to all non-sender, non-removed workspaces:
+#      - Returns {"status":"sent","delivered":N}
+#      - Receiver's activity log has a broadcast_receive entry with the message.

+Use for urgent, org-wide signals: critical status changes, emergency stop instructions, coordinated task announcements.

 Use proactively across the lifecycle of a task — early to acknowledge, mid-flight to update, late to deliver.

-"""Unit tests for OpenClaw adapter env-var key selection and provider URL routing.
+"""Unit tests for resolve_provider_routing in adapter_base.
 
-The key-selection and URL-routing logic lives inline in OpenClawAdapter.setup()
-(adapter.py lines 84-92).  Since setup() carries heavy subprocess dependencies,
-these tests isolate the selection logic by reproducing the exact Python expressions
-from the adapter source — if the adapter's logic changes, these tests must be kept
-in sync.
-
-Organisation:
-  TestEnvKeyChain          — priority order of the 3 currently supported keys
-  TestProviderUrlMapping   — model-prefix → provider URL dict correctness
-  TestNegativeAndFallback  — no keys set / unsupported keys
-  xfail stubs              — AISTUDIO + QIANFAN documented as not-yet-implemented
+Covers provider routing, URL-override precedence, and the missing-key error path.
+Each adapter defines its own registry; this test file defines one inline that
+mirrors what the openclaw adapter uses.
