* Make some managers concurrency-safe
- IntentsManager: @MainActor, non-shared, continuation
- SSIDReader: @MainActor, continuation
- Reviewer: main queue, non-shared
* Review wrong use of Concurrency framework
There were background thread calls e.g. in VPNToggle, because
ProfileManager was used inside a VPNManager async call.
Annotate @MainActor wherever a Task involves UI.
* Make main managers MainActor
* Apply MainActor to Mac menus
* [ci skip] Update CHANGELOG
* Set MainActor consistently on Mac menu view models
- Do the profile loading inside the model
- Allow setting current profile to a transient profile
- Check .placeholder before saving current profile

On iOS 14, Organizer scrolls abruptly on profile selection. It
looks like this was introduced by merging ProfilesList into
OrganizerView.
Try to revert merge to split observation responsibilities.
Drop unused AppManager in +Scene along the way.
Otherwise:
- Switch from former active profile A to B
- Connect to now active profile B
- Kill app
- Reopen app
- App shows connected to profile A
Because active profile was not saved immediately on switch.
Unnecessary now to also save it on background persist().
