feat(community): add community models for API responses

Add data models for community-related API operations:
- CommunitiesResponse and CommunityView for listing communities
- CommunityViewerState for subscription/membership status
- CreatePostRequest and CreatePostResponse for post creation
- ExternalEmbedInput for link embeds
- SelfLabels and SelfLabel for content labels (NSFW, etc.)

All models support const constructors for better performance.
