- Viewport ID uniqueness: commit_entity assigns max_existing_id+1
instead of always using id=2
- Lock/On boolean toggles in Properties panel (vp_locked, vp_on)
backed by status.locked / status.is_on fields
- Standard scale Choice picker: 1:500 to 10:1 (also syncs view_height)
- Numeric scale edit now syncs view_height when changed
- Standard view Choice picker: Top/Bottom/Front/Back/Left/Right/4×Iso
updates view_direction vector via apply_geom_prop
- Viewport content not rendered when status.is_on is false
- current_layout_block_handle_pub() added for external access
