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

+ * Tests for buildDeployMap — the pure tree-computation core inside

+ *
+ * Issue: #742 (buildDeployMap unit tests, #2071 follow-up).
+ *
+ * The function takes a flat list of NodeProjections and a set of
+ * deletingIds, then computes per-node OrgDeployState:
+ *   isActivelyProvisioning — node itself is provisioning
+ *   isDeployingRoot       — node is a root AND has provisioning descendants
+ *   isLockedChild         — node is a deleting child OR a non-root in a deploying tree
+ *   descendantProvisioningCount — total provisioning descendants (roots only)
+ *
+ * Coverage:
+ *   §1  Empty input
+ *   §2  Single node — no parent, non-provisioning
+ *   §3  Single node — no parent, provisioning
+ *   §4  Single node — has parent (parent exists)
+ *   §5  Parent not in projections → node treated as root
+ *   §6  Two nodes: root (non-provisioning) + child
+ *   §7  Two nodes: root (provisioning) + child
+ *   §8  Three-level tree: grandparent (provisioning) → parent → child
+ *   §9  DeletingIds contains a non-root node → isLockedChild=true
+ *   §10 DeletingIds contains the root → root isLockedChild=true
+ *   §11 Two independent roots, one provisioning
+ *   §12 Provisioning count: root has 2 provisioning descendants
+ *   §13 Non-root node with provisioning status → isActivelyProvisioning=true
+ *   §14 findRoot memoization: repeated calls don't re-walk the chain
+ *   §15 deletingIds + provisioning interact: deleting takes isLockedChild
+ *   §16 Child of provisioning root (not itself provisioning) → isLockedChild=true
+ *   §17 Deep chain (5 levels), no provisioning → all nodes unlocked
+ *   §18 Deep chain (5 levels), middle node is provisioning root
+ *   §19 Node with parentId pointing to non-existent node → treated as root

+ *   - isDeployingRoot: true when any descendant is "provisioning"
+ *   - isActivelyProvisioning: true only for the node itself in that state
+ *   - isLockedChild: true for non-root nodes in a deploying tree
+ *   - isLockedChild: also true for nodes in deletingIds (even if not deploying)
+ *   - descendantProvisioningCount: non-zero only on root nodes
+ *   - Performance contract: O(n) single-pass walk — tested by verifying
+ *     correctness across 50-node trees (n=50, all cases above)
