The client always called a hardcoded http://localhost:5144, which only
worked when browser and server shared the same "localhost" — breaks for
any real remote deployment, since the browser would try to reach that
port on the visitor's own machine instead of the actual server.
Now every environment routes /api/* to the server under the same origin
the page was loaded from, so the client code needs no per-environment URL:
- Docker (client container's own nginx) proxies /api/ to the server
container.
- `npm run dev` (Vite) proxies /api to localhost:5144 via server.proxy.
- Production nginx (reverse proxy + TLS) just needs to forward everything
to the client container, which already knows how to route /api itself.
Also incidentally removes CORS from the picture everywhere, since none of
these setups make a cross-origin request anymore.
On every push/PR: run Domain.Tests, then docker compose build to validate
the full stack still builds. On push to master: also docker compose up -d
to redeploy. COMPOSE_PROJECT_NAME is pinned to ruvdstests so a run from a
runner-managed checkout always targets the existing stack/volumes instead
of spinning up a duplicate under a different project name.
