Fix message spacing and remove markdown link support

- Reduce VStack spacing from 4 to 2 and nested VStack from 2 to 0
- Set list row insets top/bottom to 0 to minimize spacing on iPhone
- Remove all markdown link parsing and formatting
- Share plain URLs instead of markdown when using share extension
- Keep only plain text URL detection and preview functionality
