Add zoom, pan, and camera reset to 3D editors

Enable zoom (scroll/pinch) and pan (right-click/two-finger drag) on
all OrbitControls. Add resetView() to BaseRenderer that restores
initial camera state and auto-rotate via OrbitControls.saveState/reset.
Add reset camera button to EditorTooltip with mobile-friendly touch
targets and hover-only highlight to avoid sticky state on touch.
