qml: Enable snapshot load path setting during onboarding

- Update visibility conditions in ConnectionSettings and SnapshotSettings to enable loading during onboarding.
- Introduce new methods in NodeModel for handling snapshot file paths and loading logic based on header sync status.
- Ensure snapshot loading is triggered appropriately when headers are synced and a snapshot file path is set.
- Adds error handling on snapshot failure.
