Evaluation should include all three metrics in evalMetrics array by default

Currently, the evaluation request (evalMetrics array) in the Evaluation tab sends only one metric ('tool_trajectory_avg_score') in the request when running an evaluation. Ideally, the request should include all three relevant metrics, allowing for a more comprehensive evaluation process.

**Proposed solution:**
- Update the code to ensure the evalMetrics array is populated with all three metrics before submitting the evaluation request.
- Consider allowing the user to select which metrics to include, or include all by default.

**Impact:**
- More robust evaluation capability.
- Better alignment with expected evaluation standards.
