build: move local development off port 3000

Run the dev API on 6262 and Vite on 6263 with strictPort; production
defaults stay on 3000. Define the dev client origin once and read the
typed appConfig instead of repeating its fallback in every gateway.

-The server defaults to port 3000 (configured via `PORT` in `server/.env`) and the client to 5173 (Vite default). If either is occupied, find the process that owns it and stop it, or change the server port in `server/.env`.
+Local development runs the server on port 6262 (`PORT` in `server/.env`) and the client on 6263 (`server.port` in `client/vite.config.ts`, with `strictPort`, so Vite fails instead of silently moving). Both avoid 3000, which many other self-hosted apps and dev tools claim. A server started without `PORT`, such as the Docker image, still listens on 3000. If either is occupied, find the process that owns it and stop it, or change the server port in `server/.env`.
