[FeatureRequest] Add "Imprint" (or postmaster contact) as public menu item

Hello,

the german ISP T-Online requires me to have a direct contact information on the mail server's website (the mailu admin ui).

See: https://postmaster.t-online.de/index.en.html#t4

So it would be nice to have a configuration option for either:

• name of the public menu item + url (visual as external link) or
• add all required information to a mailu rendered imprint

It would also be nice to have the possibility to configure the help menu item url.

Thank you very much.

(i know there is the WEBSITE configuration option - but the name of the menu item cannot be changed and this option is presumably used for other stuff by other users)
