Add new documentation pages and update blog styling

This commit introduces three new documentation files: `anwendungen.md` for AI solution use cases, `stylesheets/modules/blog.scss` for blog-specific styling, and `datenschutz.md` for the privacy policy. Additionally, it enhances blog author and sidebar styling for consistency and readability.
