Fix Hugo v0.160 compatibility: remove os.Getenv and fix template syntax

- Remove os.Getenv("THEME") call that violates security policy
- Use CSS variables and data attributes for theme-aware badge colors
- Update theme-toggle.js to update badge colors on theme switch
- Fix .LastMod → .Lastmod (correct API)
- Fix template syntax for date comparison in article-header.html
