Art glow-up: all 23 hardware sprites regenerated on CF flux-1-schnell

1024px, heavily detailed component prompts (greebles, braided cables,
status LEDs, dust and scratches, neon rim light on dark charcoal) with
a shared style tail for consistency, cut with MB bg_remove_local and
autocropped. Manifest in tools/sprites.tsv, pipeline in tools/cf_cut.py.
