fix(furni): generate scale 32 from bundles with .png frame keys

resolveNitroFrame now matches spritesheet frame keys that carry a .png
suffix or namespaced naming, and isScale/scaleName preserve that suffix.
Broken source sprites (missing frames or references to icon artwork) are
skipped and reported instead of aborting the whole generation, and the
studio UI surfaces the skipped count.
