A persona's notification policy and its requests

Mastodon 4.3's policy was a stub that accepted everything. It is now kept per persona: notifications from accounts it
does not follow, accounts that do not follow it (or only for three days), accounts newer than 30 days, private mentions
it did not ask for and silenced accounts are accepted, filtered or dropped. Filtered ones stay out of every list and
count unless asked for, gathered in a request per account; letting a request in lets that account in for good,
dismissing it deletes them. Everything is accepted until the persona chooses.
