Tests panel fails with 500 on POST /api/internal/testruns when "Test Run Progress" column is enabled - invalid Test Step Status link

Description:

When the "Test Run Progress" column is added to the Tests panel of a Test Execution issue, the panel fails to load and an "Internal Server Error" toast appears. The backend crashes when computing stepsProgress because a Test Step Status on the affected site has a broken (null) link to its parent Test Status. As a result, POST /api/internal/testruns returns HTTP 500 for every Test Execution on the site. Removing stepsProgress from the fields array (i.e. not requesting the column) returns 200 successfully.

Pre-conditions:

• Xray Cloud installed on a Jira Cloud site
• The site has at least one Test Step Status whose testStatusId link is missing or not properly linked to a Test Status.
• The "Test Run Progress" column has been enabled in the Tests panel column configuration of any Test Execution

Steps to reproduce:

1. On the affected site, open any Test Execution issue in Jira Cloud
2. In the Tests panel, open the column configuration
3. Add "Test Run Progress" as a visible column
4. Observe the panel attempting to reload

Actual result/Attachments:

The Tests panel fails to render. POST https://eu.xray.cloud.getxray.app/api/internal/testruns returns HTTP 500. Browser console shows:

  Error while processing datatable data
  AxiosError: Request failed with status code 500, ERR_BAD_RESPONSE

Expected result:

The Tests panel loads successfully with the "Test Run Progress" column displayed and data populated.
