Drop permanent queue errors fast + log MAX bot add/remove events

Two queue items in send_queue could pile up indefinitely behind the
30-attempt limit and block per-destination ordering (hasPendingForChat):

  tg2max: "MAX attachment not ready after 10 retries", "must be at most"
  max2tg: "can't parse entities", "caption/message is too long"

These never become deliverable — drop them on the first failure so the
queue can drain and new messages for the same destination skip the
queued path.

Also: subscribe-listed bot_added / bot_removed updates weren't handled,
so when admins kicked the bot from a MAX chat the only signal was
silence in logs. listenMax now logs both events with chat id, actor user
id, username and display name; the DB pair is left intact in case the
bot is re-added.
