chore(golden): accept active LED core colour (#790)

Accept only the six reviewed active-LED frames from the complete canonical
WSL capture. All other baseline PNG bytes are preserved. Both off-LED
captures are byte-identical to their reviewed baselines.

Root and an independent reviewer inspected the candidates and diffs.
Separate DOM-white controls localize the intended core colour change;
residual old-baseline differences remain at Glow rims (48/74/212 pixels
above delta 10, all below the unchanged .0005 ratio threshold). Rectangle
control also records 10 baseline-to-white residual pixels and five
white-to-colour raster/repaint pixels outside the core near the door.
No claim is made that the old-baseline RGBA diff is exclusively the core,
or that the residual's historical cause has been established. No golden
threshold, product geometry, field alpha or field algorithm is changed.

Issue: #790
User-Visible: no
Release: v1.79.0
