[Bug] Need to copy commissioner_dut folder in Test Harness

Describe the bug

In Test Case DA-1.4, DA-1.8, These test cases are Vertification Steps Document.

The following is included in the Test Step of the Test Plan Verification document:
./chip-all-clusters-app --trace_decode 1 --dac_provider $CHIP_ROOT/credentials/development/commissioner_dut/invalid_paa/test_case_vector.json --product-id 32768
It indicates the use of a JSON file inside the commissioner_dut folder. However, this file is missing from the Test Harness, causing an issue where it has to be copied externally.

Therefore, we also need to copy the files in the commissioner_dut folder, as shown in the Dockerfile below.

Start by reviewing the test harness setup and the referenced integrations/docker/images/chip-cert-bins/Dockerfile section around line 433. Trace how test assets are copied, then ensure the commissioner_dut files, including test_case_vector.json, are available to the DA-1.4 and DA-1.8 verification steps without external copying.
