Update Health Check Endpoints for Liveness and Readiness

[alainncls]

Description:

The current /health endpoint is used for both liveness and readiness probes, which is not following best practices. This task involves:

1. Creating a new /live endpoint that always returns a 200 status for the liveness probe.
2. Adjusting the /health endpoint to focus exclusively on readiness checks, ensuring it validates dependencies (e.g., Infura).
3. Renaming the /health endpoint to /ready
4. Updating Kubernetes configurations to correctly use /live for liveness and /health for readiness.

Acceptance Criteria:

• A new /live endpoint is created, always returning 200.
• The /ready endpoint performs only readiness checks and reflects dependency states.
• Kubernetes configurations are updated to:
  • Use /live for liveness probes.
  • Use /ready for readiness probes.
