fix: Move FeatureChanged dialogs to Activity (WPB-3481)

[borichellow]

What's new in this PR?

Issues

Team Settings changed dialogues are only visible on conversation list.

Causes (Optional)

Feature changes were observed in HomeScreen only, so the dialogs were shown only there.

Solutions

Mode FeatureChanges observation into WireActivity.
Also extracted all the WireActivity dialogs into separate file (there are too many of them already)
