This commit:
- improves selection of addresses to reveal
- keeps the selection state for the popup lifetime
- brings higher granularity in terms of signed requests by keypairs
- meets new requirements from the latest related Figma
- merges edit shared addresses feature and request to join community features
into a single component, cause the flow is logically the same, with the only
difference that when editing revealed addresses we don't show the community
intro screen
Fixes at least points 3 and 4 from #13988
