fix: resolve deployment crashes in coordinator and API services

Coordinator: install all dependencies from pyproject.toml instead of
hardcoded subset (missing slowapi, anthropic, opentelemetry-*).

API: FederationAgentService now gracefully disables when orchestrator
URL is not configured instead of throwing and crashing the app.
