chore(golden): accept three MDI battery indicator scenes

Full 203-scene capture from published d4d48bb040
on pinned WSL/ext4 toolchain: 200 unchanged scenes and three new scenes;
105 environment witnesses passed (required floor: 10).
Reviewed light/dark boards and mobile framing against owner-approved MDI
glyphs and the designer's sizes, gaps and colors. Correct measured gzip
documentation by three bytes after the final source fingerprint settled.

Issue: #792
User-Visible: no
Release: v1.80.0-beta.4
