Bootstrap/Load: Ensure recovery link email and related notices are properly translated.

When recovery mode is triggered before the site’s locale has been initialized, the message displayed to the user and the email sent to the site administrator with the recovery mode link are always rendered in `en_US`. This change ensures the site’s locale is used even when an error happens early in the loading process.
