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.
Remove the unnecessary box-border CSS class from component template class lists across the codebase, cleaning up styling without altering any component functionality.
Remove the unused box-sizing.scss stylesheet and its import from the main SCSS index file.
Update all Vue component template class references from the custom border-box class to the
native box-border utility class to eliminate redundant custom CSS and align with the project's
utility class conventions.
Remove the unused padding.scss stylesheet and its import from the main SCSS entrypoint. Update all legacy padding utility class names across every Vue component to use inline pixel-based utility classes (such as replacing `pl-12` with `pl-[12px]`). Also clean up extraneous whitespace and line breaks in component templates for improved readability.
