Default API_BASE_URL and PROD_ORIGIN to the test environment

Previously API_BASE_URL defaulted to http://localhost:8080/api, which
only works inside the dev server proxy. For standalone/SSR runs without
the proxy, the default now points to https://flights.test.aeroflot.ru.

Dev continues to use the same-origin proxy because scripts/dev-server.mjs
explicitly injects API_BASE_URL=http://localhost:8080/api into the
Modern.js child process env, keeping browser fetches CORS/WAF safe.
