This has (as I've seen) confuse some users because we put this
information front and center. The internal room ID and it's version
isn't relevant for 99% of users, especially since most of them don't
even have permission to touch these.
Instead, let's do what Element smartly does and put it under an Advanced
page you have to intentionally find. This also has the knock-on effect
of propping up the importance of room aliases, which now appear higher
in the general settings.
This is the same functionality that /myroomnick does, but it's now
exposed in a much more accessible place in the UI. A new page to the
room settings is added to configure your profile in the room. It's
currently limited to a display name.
Use new KirigamiAddons ConfigurationsView as a replacement for
CategorizedSettings. Fix some issues on desktop when running Qt 6.8
and some less recent issues on mobile.
Visually this looks the same.
A category won't be shown if there are no relevant IDs (will add the ability to add new ones later).
