API docs and deploy script disagree on health endpoint

[RonaldRonnie]

Description:

• docs/api/README.md states “Health Check: Available at /health”
• Actuator health is at /actuator/health; with context path /api, full path is /api/actuator/health

This can confuse integration and deployment.

Acceptance criteria:

• Update docs/api/README.md (and any other docs) to state the correct health URL: /api/actuator/health
• List other Actuator endpoints (e.g. /api/actuator/metrics, /api/actuator/info) if they are part of the public API surface
