Add a few networks to fax, which send papers to request manager, and staff can answer on them from fax panel. (#71129)

## About The Pull Request

This PR adds the ability to send faxes to a central command or
syndicate, which will be delivered to the admins in request format. And
also, a fax panel for admins has been added, which will allow them to
conveniently send a fax already back (including stamps)
