🔒 [security fix] Restrict Actuator Endpoints Exposure

[Sanan507]

🎯 What: The Spring Boot Actuator endpoint (/actuator/health) was exposed on the same HTTP port as the main application and was accessible from any network interface.

⚠️ Risk: Exposing actuator endpoints on the public-facing port can lead to information disclosure. Attackers can probe /actuator/health or other endpoints if enabled, potentially gathering system state information and increasing the attack surface.

🛡️ Solution: Updated backend/src/main/resources/application.yml to restrict the actuator management server to a different port (8081) and bound it explicitly to localhost (127.0.0.1). This ensures the actuator endpoints are only accessible locally, mitigating external exposure.
