Automatically anonymize data for forms without an organization/ that were deleted by the organization

When a form is deleted by the organization (Elimină formular), all associated data should automatically be anonymized in the admin panel and the PDF should be deleted. The same is true for all forms associated to an organization that we manually delete from the admin (Șterge organizație).

Additionally, in the „Elimină formular” confirmation pop-up (see bellow), the following sentence should also be added: „Odată eliminat, un formular nu mai poate fi recuperat.”
