A brief description/summary of your PR here. What does it add? Why is it necessary? How was the change made, and how was it tested?

This pull request sets up the initial unit testing infrastructure for the boneset-api server. It adds supertest as a development dependency and creates the first test file (server.test.js) to verify the root endpoint. This is necessary to lay the foundation for future endpoint testing.

Screenshots

This is the screenshot of the tests:

Detailed Description

A more detailed description and any additional information.
I made the following changes:

Dependency: I added supertest to the devDependencies in package.json.

Test syntax: I was confused here and opted to use CommonJS (require) instead of ES Modules (import) to ensure compatibility with the existing server.js architecture and avoid refactoring the entire backend. But if you need to make that change, let me know and I'll do it.

Testing tests with npx: I noticed there wasn't a script to run tests, so I had to manually configure it using npx jest server.test.js. However, if you'd like, let me know and I'll add the script to run the tests.

I was considering making the type="module" changes and implementing the test script, but it's better to complete the specific task you assigned me first, and then you can allow me to make those changes.

And finally, a technical note: The message "Cannot log after tests are done". This is a known side effect of the asynchronous initializeSearchCache() function in server.js, which terminates after testing. Since the tests themselves passed (2/2) and I didn't want to modify the core server logic, I left it as is for this pull request.
