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

-//
-// Why this exists (RFC internal#417):
-//
-// Operators saving a vendor-scoped API key (e.g. MINIMAX_API_KEY) into
-// the platform `global_secrets` table expect the workspace to talk to
-// the canonical regional endpoint for that key. Pre-fix, when no
-// matching <PROVIDER>_BASE_URL was also saved, the adapter inside the
-// workspace fell back to its hardcoded registry default — which for
-// MiniMax is api.minimaxi.com (China), while every operator key issued
-// against api.minimax.io (global) hits 401 there. The fix is platform-
-// side: when we see the API key but no URL, we inject the canonical URL
-// so the workspace's adapter precedence chain (operator URL > runtime
-// config > adapter default) ends up pointing at the right region.
-//
-// This is a FALLBACK, never an override. If the operator already
-// saved <PROVIDER>_BASE_URL we leave it alone; their explicit choice
-// always wins. If the API key isn't set, we don't inject a stray URL
-// for a provider the workspace never uses.
-//
-// MINIMAX_BASE_URL is set to api.minimax.io (NOT api.minimaxi.com) —
