Fixes: 1) Add missing type annotations for `isSearchActive` in `useSearchUi.ts`; 2) Resolve improper conditional rendering in empty state templates across multiple files; 3) Remove unnecessary `console.log` calls in `goTo` function;
Extra: 1) Update SCSS styles including border thickness, colors, and padding tweaks; 2) Refactor `loader.vue` to use `<span>` instead of `<li>` for dots and adjust size; 3) Clean up obsolete TODOs, comments, and unused imports.
