feat: editor improvements and collapsible sidebars

Add collapse/expand toggle for the AppShell navigation sidebar and the editor properties panel (both persisted to localStorage). Bundles other in-progress editor work including position anchors, outlet sizing, PBR textures, window slope/frame depth, curtain metadata, and various 2D/3D rendering tweaks.
