[TC-DD-1.1] Add detailed instructions and verification criteria in TC-DD-1.1 script

Summary Title:

Please describe the issue briefly in few words. Also please add the SVE event info (if applicable) Example: [SVE2] Test Harness fails to pair with a thread accessory.

Description:

The Python script for TC-DD-1.1 lacks sufficient guidance for ATL representatives during test execution. The current instructions are too generic and do not clearly outline the specific actions or expected outcomes for each step.

1. Several test steps do not specify what actions the ATL representative must perform.
2. Test steps orders in Test plan and Script are not matching
3. The script lacks detailed verification criteria and expected behavior for some steps, making it difficult to validate results accurately.

Expected Behavior:

1. The script should include clear, step-by-step execution guidance for ATL representatives.
2. Each step should specify expected values, responses, or observable outcomes to assist in accurate verification.
3. Additional comments or log messages should be added in the script to guide test execution and improve readability.
