* FEATURE: Enforce mention limits for chat messages
The first part of these changes adds a new setting called `max_mentions_per_chat_message`, which skips notifications when the message contains too many mentions. It also respects the `max_users_notified_per_group_mention` setting
and skips notifications if expanding a group mention would exceed it.
We also include a new component to display JIT warning for these limits to the user while composing a message.
* Simplify ignoring/muting filter in chat_notifier
* Post-send warnings for unsent warnings
* Improve pluralization
* Address review feedback
* Fix test
* Address second feedback round
* Third round of feedback
