The AdminHeader "Clear All" notifications button has been 404'ing for
a while: frontend `notifications.service.ts` calls
`DELETE /admin/notifications/clear-all`, backend only defined
`DELETE /admin/notifications/clear-old`.
The /clear-old route was misleadingly named anyway — it tried to
delete read OR >30-days-old rows, then had a fallback that nuked
EVERY row when nothing matched. Both the frontend and the existing
test expect a simple Clear All shape, so just rename to /clear-all,
drop the tiered logic, and return the plain
`{ message, deletedCount }` payload the test asserts on.
The test (adminNotifications.test.js) was hiding the breakage —
it was on CI's --testPathIgnorePatterns ignore list and so never
ran. Two reasons it failed locally before this fix:
1. Route path mismatch (the actual #597 bug).
2. The mock only stubbed adminAuth — requirePermission lives in
its own middleware module and ran for real, 403'ing before
the handler. Add a passthrough mock for that too.
With both fixed, the test passes. Drop adminNotifications from the
CI ignore list so future regressions in this route fail loudly
instead of going to ground.
