Implement limited replies feature in NostrFeed component

- Introduced a mechanism to track posts that should display limited replies (only the first 2) instead of collapsing them entirely, enhancing user interaction with threaded discussions.
- Updated the ThreadedPost component to support toggling between limited and full replies, improving visibility and engagement with nested replies.
- Enhanced the FeedService to ensure proper filtering and handling of feed types, contributing to a more organized and user-friendly experience within the NostrFeed module.
