Restrict access to the metrics actuator endpoint

[dzmitrydd]

Description:

Fixes a security finding on uui.epam.com where /actuator/metrics was publicly accessible and exposed runtime details (memory usage, uptime, etc.).
####Changes:

1. Removed express-actuator dependency from server/package.json
2. Replaced the full actuator middleware with a minimal /actuator/health endpoint that returns { "status": "UP" } /actuator/metrics and /actuator/info are no longer exposed
