Fix LoggedLogoutView for Django 5.2 GET removal (#16317)

Django 5.2 restricts LogoutView to POST only (deprecated in 4.1,
  removed in 5.0+). Without this fix, GET requests to /api/logout/
  return 405 Method Not Allowed.

  Add http_method_names override and a get() method that delegates
  to post() where auth_logout() actually runs
