Add collapsible components and feed filter functionality

- Introduced Collapsible, CollapsibleContent, and CollapsibleTrigger components for improved UI interactions.
- Added FeedFilters component to allow users to customize content visibility in the NostrFeed.
- Updated NostrFeed and Home components to integrate new filtering capabilities, enhancing user experience with customizable content display.
- Implemented content filter logic in FeedService to support dynamic filtering based on user selections.

These changes enhance the modularity and interactivity of the feed system, providing users with greater control over the content they see.
