Fix red develop c3b67a0c47b9

The merge lane found `develop` red at `c3b67a0c47b9af77593bf7f4843b3362901c6c2e` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `frontend-unit-vitest` - … and 1 more: read them in the gate log, as untrusted output The whole gate log: artifact `8016` on lane task 8794. 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: PlanDetailPage edit test now expects the Task 8772 Your Cloud switches in the PATCH (only failing test). Vitest file 51/51, quick gate green; PR #6557 queued to merge lane.
