feat: add dark code blocks and copy buttons to documentation

Browse Source 
- Fixed white background in code blocks by adding custom CSS
  - Code blocks now use dark background (#1a1b26 for pre, #16161e for code)
  - Inline code matches theme colors
- Added copy buttons to all code blocks
  - Button appears on hover (top-right corner)
  - Shows 'Copy' → 'Copied!' feedback
  - Uses Clipboard API for copying code
- Copy buttons styled to match documentation theme

This improves the dark mode documentation experience with better
code block visibility and usability.
