Refactor and improve `GIDEMMSupport` parameters and tests

[AkshatG6]

This issue tracks follow-up improvements identified during the review of PR #608. We need to address the following technical debt and testing improvements:

• Handle nested data structures: Ensure that the parametersWithParameters function safely drops key parameters that contain values like a nested array.
• Standardize UIDevice mocking: Fix the tests that are swizzling UIDevice to "Not Do That," or ensure all tests are doing it the same way. Relying on the real UIDevice will make tests non-hermetic.
• Uplevel tests to the public API: Consider upleveling the new GIDEMMSupport unit tests to test against the public API instead of testing internal classes in isolation.
