refactor(PostCard, PostCard.legacy): remove legacy PostCard component and update exports
- Deleted the legacy PostCard component to streamline the codebase and improve maintainability. - Updated exports in PostCard and index files to remove references to the legacy component. - Adjusted PostCardProps to eliminate legacy properties, ensuring only the new API is supported. - Enhanced the PostCard component to focus on modern implementation and features.
