Using a shared channel with per-message permissions means that every client is updated with the channel's 'last_id', even if there are no messages available to them. Per-user channel names avoid this problem - the last_id will only be incremented when there is a message for the given user.

2. When you unsubscribe - remove only your subscription, not **all** subscriptions on given channel
Attempt #2. The first attempt tried to extend a core `@bound` method in new-user-narrative plugin which did not work. I reworked that plugin in the meantime. This new PR also cleans up message bus subscriptions in now core-merged chat plugin.
1. Originally the feature did "Scroll to new posts when user is near bottom of PM" (74e1889924)
2. Then that feature was limited to "Only scroll to posts that are not your own in PMs." (4a26561927)
3. It was limited further to "Only scroll PMs on new message" (eaf7746ec9)
4. And later to "only scroll to bottom for discobot" (267d129f38)
5. And the code was relegated to new-user-narrative plugin (48b7696dbc)
I don't think it's worth it to keep this scrolling code just for this very small specific case.
This did potentially confict with other post scrolling code, and also using `modifyClass` is something we'd like to avoid.

Debouncing inline anonymous functions does not work.
This fixes all instances of that error by extracting the function or using the new `@debounce(delay)` decorator
This will allow consumers to inject it using `siteSettings: service()` in preparation for the removal of implicit injections in Ember 4.0. `site-settings:main` is still available and will print a deprecation notice.
Centralizes calculations in a helper under the site header component.
This also reverts a small CSS change to the composer: since ac79c5ef,
the composer height was not including the grippie, which means that the
composer height was off by 11 pixels, and the topic progress widget was
sometimes being displayed cut off by 11 pixels.
