Refactor test scripts into scripts/ directory and improve CI

- Move run_tests_no_ot.sh and run_tests_with_ot.sh to scripts/ directory
- Create scripts/run_tests_with_coverage.py for coverage measurement
- Update CI to use scripts from scripts/ directory
- Eliminate code duplication between shell scripts and CI configuration
- Use Python script with coverage run for proper coverage measurement
