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.
- remove unused z-index and word-break SCSS utility files and their imports from src/static/scss/index.scss
- standardize padding unit notation to [px] format in ChatQuickAccess component
- reformat long class attributes and clean up whitespace in GeneratorPhotoComponent
