Web: Display ActivityPub activities and user profiles

Goal

Enable a Minds user to visually identify activities and channels that originate on third party ActivityPub services, and to navigate to their original third party-hosted homes.

What needs to be done

Remote profile badge: Implement remote profile badge wherever Minds+ / Pro badges appear, for channels which are remotely-operated (e.g. ActivityPub accounts). On hover over the icon, display tooltip that reads: {fed_domain.name} profile where fed_domain.name comes after the second @ eg: @joe**@mastodon.social** => mastodon.social. Badges can appear...
- Activity posts
- Channel pages
- Comments
- Channel recs
View original post button: On ... menus on activity posts, add a View on @{fed_domain.name}`
- Maximum of chars (16px right padding) before ellipsis (...)
- for example: View on mastodon.social. Where {fed_domain.name} is taken after the second "@" (@joe@mastodon.social)
View original profile button: On ... menus on channel pages, add a View on {fed_domain.name} button that links to the originating remote profile page (e.g. mastodon.social/@minds). Opens in a new tab.
- for example: View on mastodon.social. Where {fed_domain.name} is taken after the second "@"
  - Maximum of chars (16px right padding) before ellipsis (...)
