fix: localize 403 error dialog and handle both payload shapes

Address review feedback:
- Use i18n keys for dialog title and fallback message
- Read error detail from both middleware shape (response.message)
  and standard shape (response.error.message / response.error string)
- Add reportType for tracking
- Add accessRestrictedTitle and accessRestrictedMessage keys to all
  12 locale files (English text as fallback for non-English locales)
