Fix red develop 418e65dd26e3

The merge lane found `develop` red at `418e65dd26e3dbb0d0d08fc3c45ec3c214d03006` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `frontend-smoke-playwright-load-isolated` - … and 3 more: read them in the gate log, as untrusted output The whole gate log: artifact `8440` on lane task 9077. 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.

Fixed red develop: Worktrees hover now shows the #id title like the row (Task 9012 drift); pool e2e probes re-pointed to the shown form. 18/18 worktrees+customer e2e, quick gate green. PR #6650 queued.
