The PROD image baked PUBLIC_API_BASE_URL at build time (rsbuild inlines
PUBLIC_* vars), so a prebuilt image could only ever target a same-origin
'/api/v1' and needed a reverse proxy in front. Move the operator default to
runtime so one image can point at any backend origin without rebuilding.
- public/config.js: committed stub setting window.__APP_CONFIG__ = {}, used
as the dev/build-time default and overwritten in prod at container start.
- rsbuild.config.ts: inject a classic (non-deferred) <script src="/config.js">
into <head> so it runs before the deferred app bundle.
- src/config/env.ts: DEFAULT_API_BASE_URL now resolves
window.__APP_CONFIG__.apiBaseUrl > import.meta.env.PUBLIC_API_BASE_URL >
'/api/v1'. The user-chosen instance still wins over all of these.
- dockerfiles/30-runtime-config.sh: nginx /docker-entrypoint.d hook that
regenerates /config.js from $PUBLIC_API_BASE_URL on every start.
- Dockerfile.prod: install the hook (build-time ARG is now just a fallback).
- nginx.conf: serve /config.js with Cache-Control: no-store.
