feat(channel): integrate channel functionality into post management
- Added Channel support in Post model, including ChannelID field in PostRequest and PostResponse DTOs. - Updated PostService and PostRepository to handle channel-specific logic for creating and listing posts. - Introduced ChannelRepository and ChannelService, along with corresponding handlers for managing channels. - Enhanced router to include routes for channel management and public channel listing. - Seeded default channels in the database during initialization.
