Subject: [PATCH] Cache: fix 1-year CSS cache and add version busting

- .htaccess: remove duplicate cache block that set all CSS/JS to max-age=31536000
  CSS/JS now use max-age=3600 must-revalidate (was 1 year, breaking live edits)
- index.php: bump main.min.css version v1.1.3 -> v1.1.4
- All 78 PHP files: add ?v=20260222 to main.css and cro-enhancements.css refs
  Forces browser cache bust for all pages after todays accessibility changes
