[FR] Make tests for server.py

[DiFronzo]

Is your feature request related to a problem? Please describe.
There are currently no automated tests for server.py, making it difficult to ensure that the web server setup and logging configuration work as intended and to catch regressions during development.

Describe 1~3 use cases of the purposed feature

• Verify that the server initializes correctly, sets up logging as expected, and starts the Flask application without errors.
• Ensure that log messages are formatted and handled properly, and that log levels are respected.
• Confirm that the server can be started and stopped in a test environment without side effects or resource leaks.

Describe alternatives you've considered

• Relying on manual testing or indirect coverage through higher-level tests, but this does not guarantee that all code paths in server.py are exercised.
• Adding only integration tests, which may not catch issues specific to the server setup and logging configuration.

Additional context
Unit tests for server.py will help maintain code quality and reliability. Tests could be implemented using pytest or unittest, and should cover both typical and edge-case usage of the server initialization and logging setup.
