test(community): add tests for models, API, and screens

Comprehensive test coverage for community features:

Unit tests:
- CommunitiesResponse, CommunityView JSON parsing
- CreatePostResponse, ExternalEmbedInput serialization
- SelfLabels, SelfLabel const construction and serialization
- CovesApiService.listCommunities with pagination/errors
- CovesApiService.createPost with validation/errors

Widget tests:
- CreatePostScreen UI elements and form validation
- Character limits enforcement (title: 300, content: 10000)
- NSFW toggle, URL field show/hide behavior

Logic tests:
- Community search filtering (name, displayName, description)
- Member count formatting (K/M suffixes)
- Description line building with separators
