Fix red develop d584e1fae53f

The merge lane found `develop` red at `d584e1fae53f445edd5b57f317607a07c38aefc3` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `tests/test_data_access_events.py::test_the_recording_seam_is_the_only_app_caller_of_opened_config` - `tests/test_durable_enqueue_engine.py::test_the_same_workflow_id_enqueued_twice_through_the_seam_attaches_to_one_workflow` - `tests/test_support_comments.py::test_a_ticket_mention_reaches_the_inbox_and_an_internal_one_only_operators` - `tests/test_tenant_gmail.py::test_no_dispatch_or_runner_path_can_read_a_tenant_gmail_secret` - `api-unit-dc-test` The whole gate log: artifact `15375` on lane task 13453. Make `develop` pass its full gate again. Open a PR as usual: the merge lane merges a PR that fixes some of these and adds no failure even while `develop` is red.

PR #7905 (queued) fixes the remaining reds: stale durable-destroy and Easy Mode switch pins, plus a Gmail-census comment trip. Develop had fixed the other named reds; two were flakes. Quick gate and full API suite green. Memory: used mem-25288.
