fix(timeline-chart): update import statement and add noqa comment for clarity

- Removed unnecessary noqa directive from LoadSaveWidget import in configuration_management_system.py.
- Added noqa comment for private member access in timeline.py to address linting concerns.

These changes improve code clarity and maintain compliance with linting standards.
