Make PATH addition optional in installer and remove unwanted screens

- Change installer UI from WixUI_Minimal to WixUI_FeatureTree to show feature selection
- Create separate 'Add to PATH' feature that users can select/deselect
- Default PATH addition to enabled (Level=1) but allow user choice
- Skip license dialog since we don't have a license file
- Update completion message to be conditional on PATH selection
- Apply changes to all installer scripts:
  - GitHub workflow (.github/workflows/build-installers.yml)
  - Test script with UI (test-windows-installer-with-ui.ps1)
  - Main test script (test-windows-installer.ps1)

Users now get a clean installer experience with optional PATH addition.
