refactor: migrate legacy color classes to inline tailwind text utilities

Replace all usages of legacy `.color-*` and `.text-color-*` SCSS utility classes with inline Tailwind `text-[#hexcode]` arbitrary value classes. Remove the deprecated `src/static/scss/colors.scss` file, and fix minor formatting/indentation issues across multiple component files.
