Add prose styling for documentation content

The prose classes from @tailwindcss/typography weren't working because
the plugin wasn't installed. Added custom prose styling for:
- Proper paragraph spacing (mb-4)
- Header margins (mt-10 for h2, mt-8 for h3)
- Lead paragraphs styling
- List styling with proper indentation
- Code block styling (dark theme)
- Inline code styling
- Table styling
- Blockquote and details styling
