style: add Tailwind Typography plugin for proper markdown rendering

Installed @tailwindcss/typography plugin to fix 'wall of text' issue in documentation.
The prose classes now properly style markdown HTML elements with:
- Proper margins and spacing for headings, paragraphs, lists
- Line-height and typography improvements
- Styled code blocks, blockquotes, tables, and links

Changes:
- Add @tailwindcss/typography to devDependencies
- Configure plugin in tailwind.config.ts
- Regenerate CSS with typography styles included
