Add web/ with React 19, TypeScript, Vite, React Router 7 and TanStack
Query 5. Scripts: dev, build (tsc --noEmit + vite build), preview,
typecheck and test (Vitest run, jsdom, Testing Library). The dev server
proxies /api, /auth and /media to http://localhost:8080. App renders a
placeholder "MealQuest" shell covered by a smoke test. package-lock.json
is committed; node_modules and dist stay ignored.
