Fix flake8 linting errors in Python scripts

- Remove extra blank lines in memory-leak-monitor.py (E303)
- Fix continuation line indentation in memory-leak-monitor.py (E128)
- Remove whitespace from blank lines in performance-regression-detector.py (W293)
- Replace print() with logger.info() in apply-db-migration.py (NP100)

All scripts now pass flake8 linting checks.
