feat(menu-app): full redesign to Olive & Thyme design spec

Rebuild the public-facing digital menu from the design handoff bundle.
Matches high-fidelity spec: Bricolage Grotesque + Hanken Grotesk fonts,
cream/green/gold palette, per-category tinted panels, product cards with
gradient art, tag icon badges, bottom-sheet product detail, search overlay,
cart → checkout bottom-sheet flow posting to real API, floating cart button
with bump animation, and restyled order-confirm page.

- New: src/components/primitives.jsx (DishArt, Badge, DietChip, TagIcons,
  Price, DiscountFlag, Stepper, price helpers)
- Rewrite: MenuPage.jsx — all screens in one component tree, API-driven,
  lang toggle (EN/GR) persisted to localStorage, scroll-spy category bar
- Rewrite: OrderConfirm.jsx — design-system styling, brand colors
- Update: App.jsx — remove /order route (cart flow is now a bottom sheet)
- Update: tailwind.config.js — font families, brand tokens, animations
- Update: index.html — Google Fonts for Bricolage Grotesque + Hanken Grotesk
- Delete: CartPage, ProductModal, ProductCard, CategoryNav, CartButton

Cart checkout POSTs to real submitOrder API and redirects to /confirm/:ref
for live order status polling. Restaurant info falls back to hardcoded
placeholder until backend includes it in the fetchMenu response (see
REWORK_REVISIT.md).
