SectionAxisDialogManager:
- Update activateSectionAxis → activeSection in callbacks

SectionBoxDialogManager:
- Update activateSectionBox → activeSection('box')
- Disable fitSectionBoxToModel and resetSectionBox (not supported)

SectionPlaneDialogManager:
- Add activeSection('face') to onDialogCreated
- Add deactivateSection() to onBeforeDestroy
- Wire onHide to engine.clipping.disabled()
- Keep onReverse/onReset as log-only (not supported)
