Template workflows were not centering on view when loaded because they
contained saved view position data (extra.ds) from when they were created.
This fix adds a centerView option to loadGraphData that forces centering
regardless of saved view state.
Changes:
- Add centerView option to loadGraphData function
- Update view restoration logic to prioritize centering when centerView is true
- Pass centerView: true when loading template workflows
- Add test to verify centerView option is passed correctly
