v1.4.7

- Accept hyphens in element names: AC254-050-A and AC254_050_A are
  interchangeable in the GUI (#510)
- Fix magnification gating: was gated on fieldOfView instead of
  isImaging — bare Lens(f=100) showed Inexistent for magnification
  despite it being -1.0 (#509)
- Fix z-tracking for thick elements: get_path_from_ui didn't account
  for element thickness when computing Spaces, shifting the image
  plane for doublets (#509)
- Guard RESULT_ROWS lambdas with try/except for transient states
- macOS code signing and notarization in CI (when secrets are set)
