refactor(PostCard, PostCardGrid, HomeScreen): enhance PostCard component and remove PostCardGrid

- Introduced a new PostCardRelativeTime component for dynamic time display, improving user experience with real-time updates.
- Refactored PostCard to utilize memoization for performance optimization and prevent unnecessary re-renders.
- Removed the PostCardGrid component to streamline the codebase, consolidating functionality within the PostCard component.
- Updated HomeScreen to leverage the new PostCard features, ensuring consistent post rendering and interaction handling.
