feat(clipping): implement hide/recover toggle for all section dialogs

Update all three section dialogs to support hide/show toggle:

SectionAxisDialogManager:
- onHideToggle now calls hideSection()/recoverSection()

SectionBoxDialogManager:
- onHideToggle now calls hideSection()/recoverSection()

SectionPlanePanel:
- Add isHidden state tracking
- Change onHide to onHideToggle(isHidden)
- Add setHiddenState/getHiddenState methods
- Update button to toggle active state

SectionPlaneDialogManager:
- Switch to onHideToggle callback
- Call hideSection()/recoverSection() based on toggle state

Behavior: Click hide button to hide section, click again to recover.
