Add a Containers tab (bottles-and-containers: cans, jars, mugs)

add 3 static-asset tabs (pallet_boxes, gas_cylinder, pallet_racking) + generalize class-scenes -> class-static so their HF-link panel replaces the articulation UI

add Scenes tab: bedroom / kitchen / garage room GLBs from scenes-and-worlds dataset

Point at the new consolidated datasets (warehouse-manipulation-and-states + articulated-storage-and-appliances); ship per-class viewer catalogs in the space; add ovens.
