Healthcheck broken for streaming

[damienlaine]

Description

When using SERVICE_MODE=websocket, the current implementation does not properly handle health checks, leading healthcheck fail streak in orchestrated deployments.

---

Current Behavior

• Health checks fail when SERVICE_MODE=websocket is selected. The documentation is inconsistent:
  • Kaldi implementation service mode documentation
  • Whisper implementation service mode documentation

---

Questions to Address

1. Failback Implementation: Should we default to SERVICE_MODE=http and use it in combination with ENABLE_STREAMING to achieve streaming?
2. Potential Drawbacks:
   • Could this approach introduce additional latency, system load, or other unexpected issues?

---

Expected Outcome

• A robust health check mechanism that works seamlessly, regardless of the SERVICE_MODE.
• Clear and unified documentation of expected behavior for each SERVICE_MODE.
