fix: onboarding improvements — auto port detection, better error messages, CI fix

- Auto-detect WebAPI on port 8642/8643 (no HERMES_API_URL required)
- Connection error shows specific WebAPI install instructions
- CI: --no-frozen-lockfile to match Docker setup
- .env.example documents all config options
- Startup log shows configured API URL
