Andrei Prigorshnev 62f423da15 DEV: Redesign chat mentions (#24752) ... At the moment, when someone is mentioning a group, or using here or all mention, we create a chat_mention record per user. What we want instead is to have special kinds of mentions, so we can create only one chat_mention record in such cases. This PR implements that. Note, that such mentions will still have N related notifications, one notification per a user. We don't expect we'll have performance problems on the notifications side, but if at some point we do, we should be able to solve them on the side of notifications (notifications are handled in jobs, also some little delays with the notifications are acceptable, so we can make sure notifications are properly queued, and that processing of every notification is fast enough to make delays small enough). The preparation work for this PR was done in fbd24fa, where we make it possible for one mention to have several related notifications. A pretty tricky part of this PR is schema and data migration, I've explained related details inline on the migration files.		2024-01-17 15:24:01 +04:00
