Deploy script health check uses wrong path

[RonaldRonnie]

Description:

scripts/deploy.sh checks application startup with:

curl -s "http://localhost:$PORT/api/health"

Spring Boot Actuator exposes the health endpoint at /actuator/health. With server.servlet.context-path=/api, the correct URL is http://localhost:$PORT/api/actuator/health, not /api/health. The script may incorrectly report failed startup or hang.

Acceptance criteria:

• Health check in deploy.sh uses /api/actuator/health (or the actual health URL from config)
• Deployment docs (e.g. docs/deployment/README.md) list the correct health URL
