Subject: [PATCH] fix: update deprecated Sass functions to modern syntax

Replace deprecated Sass functions with modern alternatives to prepare
for Dart Sass 3.0.0 and eliminate build warnings:

- Replace lighten() and darken() with color.adjust()
- Replace transparentize() with color.adjust($alpha)
- Replace red(), green(), blue() with color.channel()
- Replace mix() with color.mix()
- Replace map-merge() with map.merge()
- Replace index() with list.index()
- Replace nth() with list.nth()

Files modified:
- src/scss/_variables.scss
- src/scss/_general.scss
- src/scss/_generic.scss
- src/scss/menu/_menu-lite.scss
- src/scss/mixins/_function.scss
- src/scss/mixins/_buttons.scss
- src/scss/theme-elements/_data-tables.scss
- src/scss/theme-elements/_labels-badges.scss
- src/scss/theme-elements/_radiobox-checkbox.scss
