Not converted in this pass — scope-reduced under time constraints, not silently dropped.

Source doc: `~/Downloads/ADMIN_Tasks_Test_Case_Documentation.txt`.
Source scripts to port from (chibistar/automation/starr/): `test-tasks-admin.cjs` (589 lines),
`test-tasks-admin-part2.cjs` (308 lines), `test-tasks-admin-part3.cjs` (326 lines),
`test-tasks-admin-part4.cjs` (162 lines) — ~1400 lines total, largest of the five modules
originally scoped for this pass. Follow the same conversion pattern used in
`../courses/admin.spec.js` and `../advertisements/admin.spec.js`: rebuild as one
self-contained `test.describe.serial` spec using fresh `[QA-TEST]`-tagged fixtures
per run (the source scripts assume specific pre-existing live state / prior-run
leftovers, which isn't safe to replay unattended in CI).
