chore(apps): remove unused code and packages (DEAD-01, DEAD-02, DEAD-03)

Owner approved the deletions. Found by walking imports from each app's
main.ts; sw.ts stays (the PWA plugin's entry).
- user-app: 8 unreachable components, loadingStore.
- user-app-v2: 11 unreachable components, loadingStore.
- both: the unused validators and price helpers, and the gsap and
  @ant-design/icons-vue packages.
- the stray root user-app-v2/ folder (an old package.json and
  vite.config.ts that nothing referenced).
Both apps type-check clean.

-  Ported from legacy henza_pwa/src/components/ui/ScrollFetchAfterSearch.vue.
-  Legacy imported emp_after_search.svg / emp_before_search.svg and an `isSearch`
-  prop to pick between them, but the live template used neither — it rendered
-  `ordersEmpty.svg` unconditionally. Ported as-is (unused imports dropped,
-  `isSearch` kept since it is part of the component's declared prop contract).
