fix(hexojs): Remove /blog root path, use / as root

Change all hardcoded /blog/ paths to use / as root:

Theme configuration:
- _config.yml: Menu paths now /cybersecurity/ instead of /blog/cybersecurity/
- Blog submenu path changed to /categories/

Layout templates:
- post.ejs: Category link uses url_for with root path
- index.ejs: "Voir le blog" links to /categories/
- category.ejs: Breadcrumb and back links use /categories/

Scripts:
- dynamic-blog.js: Category paths now /{slug}/ instead of /blog/{slug}/
- Menu blog path changed to /categories/

Presets:
- tech.yml: Menu paths updated
- portfolio.yml: Blog link updated

hexoctl:
- Default portal_path changed from /www/blog to /www
- Help text updated

This allows the blog to be served from the root URL with categories
at /{category}/ paths.
