What type of PR is this?

• tests

What this PR does / why we need it:

Adds one .feature file per operation of sample-service under code/Test_definitions/, adapted from the Commonalities r4.4 testing artifacts (sample-service-template.feature, C01-device-errors.feature). Each file covers the success path and the error responses documented for that operation in sample-service.yaml, and nothing beyond them.

• Validation now runs the Gherkin engine on this repository; P-006 ("No .feature test file found") no longer fires.
• The files give a concrete, lint-clean adaptation of the templates that can be contributed back to Commonalities.

Which issue(s) this PR fixes:

None.

Special notes for reviewers:

The adaptation already includes the changes proposed in camaraproject/Commonalities#727 (response header checks and their order) and camaraproject/Commonalities#732 (request body strictness, for createResource). For the invalid x-correlator scenarios the response x-correlator echo is not checked, pending the open question in camaraproject/Commonalities#726.
