fix(editor): shelf deletion plays item-delete SFX; refresh delete sounds (#379)

* fix(editor): shelf deletion plays item-delete SFX; refresh delete sounds

Shelves are furniture-like placeable objects, so deleting one should use
the lighter item-delete cue instead of the structure-delete one. Add a
shared emitDeleteSFX(nodeType) helper that maps item-like node types
(item, shelf) to item-delete and everything else to structure-delete,
and route the three delete sites (sledgehammer, floating action menu,
keyboard) through it.

Also refresh the item_delete/structure_delete audio assets and reduce
their pan jitter for a steadier delete cue.
