fix(ci): Execute tests via web server This commit fixes the test execution by running the tests in a proper web context. Previously, the tests were run via the PHP CLI, which caused errors because the $_SERVER variables were not being set. This has been resolved by: 1. Starting a PHP built-in web server in the background. 2. Using curl to make an HTTP request to the test/index.php script. 3. Parsing the output of curl to determine if the tests passed or failed. 4. Adding a step to stop the web server after the tests are complete. This approach correctly simulates a web environment, allowing the tests to run as intended.
