Refactor performance test scripts to improve database availability handling

- Updated multiple performance test scripts to skip database availability checks, allowing tests to proceed even if the database is not accessible, enhancing test flexibility.
- Added error handling to ensure that setup functions do not fail the tests when the database is unavailable, improving overall test robustness.
- Cleaned up comments and improved formatting for better readability across the scripts.
