Migrate frontend to Vuetify/Vuexy + add real WHMCS product data

- Migrate all frontend from plain JS/Tailwind to TypeScript/Vuetify 3 (Vuexy design system)
- Replace placeholder plans with 25 real products scraped from WHMCS:

  4 web hosting plans ($2.39-$15.99/mo), 4 MySQL hosting plans ($6-$30/mo)
- Fix Pricing page: correct field mapping (service_type, price), display
  feature values instead of keys, proper price formatting
- Update all marketing pages (Home, Products, VPS, Dedicated, Web Hosting)
  with real specs, pricing, and features from production WHMCS
- Add 38 Vuexy @core SCSS override files for component styling
- Create 4 layouts (Account, Admin, Auth, Marketing) with Vuetify
