fix: update Gemini model configurations for better stability

- Changed model configurations for primary_agent, assistant, refiner, adviser, and pentester to use `gemini-2.5-pro`, enhancing performance with adjusted temperature and top_p values.
- Updated pricing parameters for various models to reflect new pricing structures.
- Revised the test report to include updated success rates and average latencies, ensuring accurate performance metrics for all agents.
- Improved overall test results with enhanced latency measurements across multiple test cases.
