[MERGE][IMP] mail, mail_bot: improve Discuss onboarding and add your new best friend

Purpose of this merge is to improve onboarding of Discuss. This is done via
a wow effect and a bot to test the Discuss app; otherwise you have nobody to
talk to. Purpose is also to improve retention as "the best way to increase
retention is this: when the user invites someone, when this guy activates its
account, the user gets a push notification from the invited user that just
logged in; that way he will come back to Odoo and start discussing with its
colleagues.

Concerning your new best friend: it is not a dog but Odoobot.

See sub commits for more details. This merge is linked to task ID 1838588 and
closes PR #25075.
