Consolidate and modernize SCSS into global styles

Move component-level styles into src/styles.scss and remove duplicated rules from several component SCSS files (app, topbar, about, algorithms, sorting, imprint, project dialog, projects, babylon-canvas). The global stylesheet now centralizes layout and typography (clamp-based sizing), sorting visualization & canvas rules, topbar/menu overrides, project/swiper styles, and shared utilities. This reduces duplication, improves responsiveness, and simplifies stylesheet management.
