Refactor MkDocs blog structure, enhance SCSS watcher, and improve plugin configuration (#103)

- Adjusted `mkdocs.sh` to expand SCSS watcher to include `docs` and `mkdocs.yml`.
- Simplified blog template by extracting post logic to `partials/post.html`.
- Updated `mkdocs.yml` with refined plugins including RSS, meta, and enhanced blog options.
- Improved blog Markdown files with structural changes and better TOC handling.
- Removed unused styles and deprecated logic in blog posts for cleaner maintenance.
