fix: code blocks rendering + consistent styling with ciphera-website /learn

- Convert MDX CodeBlock components to standard markdown code fences
- Add rehype-mdx-code-props to pass filename meta to code components
- Custom pre/code MDX components map fences to CodeBlock
- Add brand color badges (product + category) matching /learn layout
- Match prose styling: orange inline code, orange links, white strong
- Remove brand color background glow (not in /learn)
