When right-clicking a community from the navbar and selecting "View community", Status Desktop
opens `CommunityMembersPopup` which looks like it was either never really finished or more of an
intermediate solution until a proper community profile popup was created.
That's why this commit replaces it with a `CommunityProfilePopup` instead.
In fact, this lead to changes in `CommunityProfilePopup` where the `activeCommunity` dependency
is entirely removed, which allows us to use this popup in various places given that it's hydrated
with proper data.
Because we're no longer relying on `activeCommunity` inside that popup, all of its children and
connected popups needed that same refactor as well, hence this PR introduces a few more changes.
Closes#2890
