Propagate Jenkins custom parent ID

[juan-fernandez]

What Does This Do

Adds Jenkins CI Visibility propagation for DD_CUSTOM_PARENT_ID through the existing _dd.ci.env_vars serialization path, alongside DD_CUSTOM_TRACE_ID.

Motivation

The Jenkins plugin exposes DD_CUSTOM_PARENT_ID so backend correlation can compute job correlation IDs from both the custom trace ID and parent ID. The Java provider was only passing the trace ID.

Additional Notes

Updated the Jenkins fixture expectations and the supported configuration metadata entry for DD_CUSTOM_PARENT_ID.
