Remove debug System.out.println from ApplicationStartupTimeService

[coderabbitai]

Description

Remove the temporary debug System.out.println statement from ApplicationStartupTimeService.java that prints the startup time to stdout.

Location

• File: src/main/java/com/divudi/service/ApplicationStartupTimeService.java
• Line: 25

Task

Delete the following line:

System.out.println("Application started at: " + startupTime);

This will prevent startup noise in production logs while keeping the functional startup time tracking intact.
