Admin-only page to promote/demote/verify/unverify a user by id. Actions proxy
to the userservice forwarding the admin's session JWT, which the userservice
re-checks (defense in depth). Non-admins are redirected off the panel; the
Admin link shows only for admins. Admins already see all jobs on the dashboard.
Tests: requireAdmin gate, bearer forwarding, action/id validation, admin link.
