fix: don't pre-render view and comment count components

- Introduced a new PostStats component to handle view and comment counts, replacing the previous async implementation with a client-side approach.
- Updated CommentCount component to use client-side state management for fetching comment counts.
- Removed unnecessary caching logic from view and comment fetching functions.
- Simplified date formatting by moving it inline, enhancing performance and readability.
