Currently, each service has to deal with a user's PGP settings when sending an email. Instead, have meta.sr.ht provide an internal API endpoint for sending an email, centralizing all PGP handling in meta.sr.ht.
Side note: once it exists, use this API also for sending the PGP test email in meta.sr.ht itself and check if the python code path for sending encrypted emails can be removed.
