Subject: [PATCH] [ISSUE #401 #405] Support runtime API base URL configuration
for Docker
The frontend API base URL was hardcoded at build time, causing issues
when deploying via Docker (the built image always points to
localhost:8082). This commit introduces a runtime configuration
mechanism:
- Add env-config.js loaded before React app, providing window.__ENV__
- Update remoteApi.js to check window.__ENV__.API_BASE_URL first
- Add Docker entrypoint script that extracts and patches env-config.js
when API_BASE_URL environment variable is set
- Users can now set API_BASE_URL in docker-compose to configure the
frontend at container startup without rebuilding
This fixes both #401 (Docker localhost issue) and #405 (release API
localhost:8082 issue).
