Cambios en "Archiving and anonymising processes [admin comfort + traceability + GDPR]"

Is your feature request related to a problem? Please describe.
Some platforms have more than 100 consultations, the vast majority of which are trials/tests that are no longer used. Also, for reasons of compliance with the General Data Protection Regulation (GDPR) and respect for privacy, it is necessary to archive certain consultations and anonymize their content.

Describe the solution you'd like
Create a new tab dedicated to archived processes and create a button next to every process that allows you to archive it. When a process is archived, it will remain visible to the public but under a different tab in both the front office and back office, unless the admin unpublishes it.

Using an environment variable, we can define the time period after which an archived consultation will be automatically anonymized. However, the administrator can anonymize a consultation in advance. Anonymization would consist of dissociating user accounts from proposals, debates, comments, support, and other associated elements.

Describe alternatives you've considered
Having the possibility to delete processes.
