Fix red develop 26d4b3328048

The merge lane found `develop` red at `26d4b33280481be551193835cea22d3c1a24f8eb` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `tests/test_jaah_extension_spec.py::test_the_file_is_the_table_projection` - `frontend-unit-vitest` - `jaahd-unit-pytest` - … and 3 more: read them in the gate log, as untrusted output The whole gate log: artifact `8895` on lane task 9322. 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.

Regenerated agent-sdk jaah-extension.json and TaskEditForm snapshots for the marketer persona (#6722 missed both); quick gate green, both failing stages pass locally. PR #6724 queued on the merge lane. Memory: none applied.
