feat: enhance zap display with RichText context and scrollable details

Improvements:
- Pass zap request event as context to RichText components
  - Enables proper mention/link resolution in zap messages
  - Supports interactive elements (mentions, hashtags, links)
  - Provides full event context for rendering
- Make transaction detail dialog scrollable
  - Add max-h-[90vh] to DialogContent with flex layout
  - Wrap content in overflow-y-auto container with max-h-[calc(90vh-8rem)]
  - Prevents dialog overflow when displaying large zapped posts
  - Smooth scrolling for long zap message threads
- Reduce transaction page size from 20 to 10
  - Better performance with rich zap rendering
  - Faster initial load and scroll rendering
  - Reduces memory footprint for transaction list

Technical changes:
- Add zapRequestEvent field to ZapRequestInfo interface
- Pass zapRequestEvent to all RichText components rendering zap messages
- Update BATCH_SIZE constant from 20 to 10
- Add flex layout to DialogContent for proper scrolling
- Add pr-2 padding to scrollable container for visual spacing
