fix: core flow prerequisites - diagnosis API, healthcheck, agent framework optional

- Fix frontend diagnosis.ts: add triggerGEODiagnosis (POST), fix getGEODiagnosis to use /result endpoint
- Make agents_router conditionally registered (agent_framework optional)
- Replace curl with Python urllib in Docker healthcheck (no curl dependency)
