feat: integrate applesauce-content for proper content parsing and rendering

- Install applesauce-content package for content parsing
- Use getParsedContent() to parse nostr content according to applesauce patterns
- Create proper TypeScript interfaces for ParsedNode and ParsedContent
- Add renderParsedContent() component to render parsed content with proper styling
- Handle mentions, links, and text content with appropriate styling
- Add CSS styles for nostr-mention and nostr-link classes
- Follow applesauce-content documentation patterns for content rendering
- Maintain type safety with proper interfaces instead of 'any' types

This follows the applesauce-content documentation exactly as shown
in the examples, providing proper content parsing and rendering.
