feat: upgrade to v1.3.2 with settings panel overhaul, clear height enhancements and bug fixes

- Overhaul settings dialog: add edge line toggle, contrast/saturation/light intensity sliders, environment and ground type selectors
- Add clear height measurement options: direction (up/down) and select type (point/element) with radio button UI
- Fix right-click context menu triggering during model drag rotation (add move threshold)
- Fix measure dialog event listener leak (on → off for cleanup)
- Update mini map API to use engine.minMap.toggle()
- Replace text-based measure icons with proper SVG assets (净高/净距/坐标/面积)
- Add i18n keys for all new settings and clear height options (zh-CN / en-US)
- Bump iflow-engine-base dependency to ^2.0.5
- Rebuild dist and sync demo libs
