David Parry e2a9ef9bbf feat: proxy backend API through Next.js using runtime BACKEND_URL
Previously, NEXT_PUBLIC_API_URL was a build-time Next.js variable, making
it impossible to configure the backend URL in docker-compose `environment`
without rebuilding the image.

This change introduces a proper server-side proxy:
- next.config.ts: adds a rewrite rule that forwards all /api/* requests
  to BACKEND_URL (read at server startup, not baked at build time).
  Defaults to http://localhost:8000 so local dev works without config.
- api.ts: API_BASE is now an empty string — all fetch calls use relative
  /api/... paths, which the Next.js server proxies to the backend.
- docker-compose.yml: replaces NEXT_PUBLIC_API_URL build arg with a
  runtime BACKEND_URL env var defaulting to http://backend:8000, using
  Docker's internal networking. Port 8000 no longer needs to be exposed.
- README: updates Docker setup docs, standalone compose example, and
  environment variable reference to reflect BACKEND_URL.

// All API calls use relative paths (e.g. /api/flights).
// Next.js rewrites them at the server level to BACKEND_URL (set in docker-compose
// or .env.local for dev). This means:
// - No build-time baking of the backend URL into the client bundle
// - BACKEND_URL=http://backend:8000 works via Docker internal networking
// - Only port 3000 needs to be exposed externally
