- Updated PostHandler to include channel information in post responses. - Introduced PostChannelBrief DTO to represent channel details associated with posts. - Modified post conversion functions to support channel data, ensuring proper mapping of channel IDs to channel names. - Enhanced ChannelRepository and ChannelService to facilitate batch retrieval of channels by IDs. - Updated wire generation to inject channel service into post handler for improved functionality.
