Pass Real Data to callGenerateReport in TaskQueueView

This commit updates the `TaskQueueView` to pass real data from the `selectedNodeHierarchy` to the `callGenerateReport` method in `SkillTreeViewModel`. An array of test names is constructed from the reversed node hierarchy, and these names are used as the `tests` field in the `ReportRequestBody`.

Note: The `category` field is now an empty string as per the new requirement, and `mock` continues to be set to true.
