fix: resolve 405 Method Not Allowed errors in user management API calls

- Fixed changeUserRole: changed PATCH to PUT to match backend endpoint
- Fixed toggleUserStatus: changed PATCH to PUT to match backend endpoint
- Backend uses HttpPut for both endpoints, frontend was using wrong methods
- Now all user management operations should work without 405 errors
