Is your feature request related to a problem? Please describe.

Currently, the "Download CSV" functionality in the Suite tab exports many test execution details but does not include a "Success Rate" column. The success rate is a crucial metric for analyzing test stability over time and should be available in the exported data.

Describe the solution you'd like

• Add a new "Success Rate" column to the CSV export in the Suite tab.
• The "Success Rate" is currently available in test run details -> history tab

• The idea would be including that metric in the Suite tab Download CSV funtionality

Additional context

• The UI already displays the success rate; this request is to make it available in the exported CSV as well.
• Provides a quick and easy way to analyze test pass rates.
• Helps teams monitor test stability and identify problematic suites.
• Reduces manual effort required to calculate success rates from the exported data.
