feat: add attestation events to LocalCache, Home feed, profile feed, and NoteCompose UI

- Load AttestationEvent (31871), AttestationRequestEvent (31872),
  AttestorRecommendationEvent (31873), and AttestorProficiencyEvent (11871)
  into LocalCache via consumeBaseReplaceable
- Create beautiful card-based UI renderers for all four attestation types
  with color-coded status indicators, validity badges, and kind chips
- Add attestation kinds to Home feed data source (FilterHomePostsByAuthors)
  and DAL filter (HomeNewThreadFeedFilter)
- Add attestation kinds to user profile feed data source
  (FilterUserProfilePosts) and DAL filter (UserProfileNewThreadFeedFilter)
- Add string resources for attestation status labels
