Drop Less support: The style.less and themes/libreqr/theme.php files are converted to plain CSS.
The main Less features used in LibreQR were variables and selector nesting, but since CSS custom properties and nesting are now widely supported across browsers, the less.php dependency can be ditched.
To read the background color for contrast improvement, a regex is used on the theme CSS file.
