Refactor 'listExpiringTokens' and 'listExpiredTokens' to reduce code duplication

As per [PR #3634](https://github.com/airqo-platform/AirQo-api/pull/3634), the methods `listExpiringTokens` and `listExpiredTokens` in `src/auth-service/utils/control-access.js` have similar structures and logic, differing mainly in the function called (`getExpiringTokens` vs. `getExpiredTokens`). It is suggested to refactor these methods into a single reusable function or higher-order function that accepts a parameter to differentiate the behavior. This will enhance maintainability and reduce redundancy.
