fix(#337): Add API key authentication for orchestrator-coordinator communication

Browse Source 
- Add COORDINATOR_API_KEY config option to orchestrator.config.ts
- Include X-API-Key header in coordinator requests when configured
- Log security warning if COORDINATOR_API_KEY not configured in production
- Log security warning if coordinator URL uses HTTP in production
- Add tests verifying API key inclusion in requests and warning behavior
