Update task statuses and enhance test runner compatibility

- Marked tasks for improving source code documentation and fixing critical process startup issues as done.
- Updated the status of individual failing tests to in-progress.
- Refactored test runners in `conftest.py` to use `python3` and absolute paths for better compatibility in container environments.
- Added debug logging in `BaseReplicationTest` to improve error handling and visibility during test execution.
