PR Summary

WHAT Changed

• Updated the application.yml configuration file to change the server port from the default to 9090.

WHY It Matters

• Changing the server port allows the application to run on a different port, which can help avoid conflicts with other applications that may be using the default port (usually 8080).

RISKS

• Potential conflicts with existing services running on port 9090.
• Other components or services that rely on the previous port may fail to connect.

TESTS to Add

• Verify that the application starts successfully on port 9090.
• Ensure that all endpoints are accessible and functioning as expected on the new port.
• Test for any integration points that may be affected by the port change.

BREAKING CHANGES

• The application will no longer be accessible on the previous default port (if applicable). Users and services relying on the old port will need to be updated to use port 9090.
