test: improve test script with unique names and random ports

- Remove python3 dependency for port selection
- Use RANDOM for port selection in range 20000-30000
- Use unique container names based on PID: grasp-audit-run-294183
- Use unique temp directories: grasp-audit-run-XXXXXXXXXX
- Ensures parallel test runs don't conflict
