ci: disabling tests with maybe function for CI environments

The `maybe` function has been introduced in the `fts.spec.ts` test file to skip tests when in a continuous integration environment. The beforeAll hook using delay has been removed, since test cases are either run or skipped based on the process environment, thereby improving test execution efficiency
