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.
