PR Summary

• Organized Test Files Better
  The labels of some groups of test files were updated to better represent what they're testing. This is equivalent to renaming folders in a filing cabinet to accurately represent what's inside. Thus, enhancing maintainability and understandability of the test suite.
  • The tests for working with "Assets" were moved from the 'Feature/Assets/Ui' group to the 'Tests/Features/Assets/Ui'.
  • The tests for "Checkouts" moved from the 'Feature/Checkins/Ui' group to the 'Tests/Feature/Checkouts/Ui'.
  • The tests for creating and viewing "Licenses" moved from 'Feature/Consumables/Ui' to 'Tests/Features/Licenses/Ui'.
  • The tests for handling locations in the API moved from 'Feature/Consumables/Api' to 'Tests/Feature/Locations/Api'.
    These changes contribute to making the test files easier to find and work with in the future.
