Overview

Builds the Image Profile Manager "Image Library" list in priority order:

  1. Images linked directly to the item
  2. PL×PC ladder — for each PL node (leaf→root on primary PL, then constellation PLs), each PC
    node (leaf→root), then PL-only for that node (see Item::ImageLibraryPlPcLadder)
  3. Images linked to sibling items (same primary PL + same product category)
