Counterpart to RunicGateway/website#77.
- BACKEND_DESIGN.md: /public table now documents the new GET /public/version
(DB-free identity/version), the version block on /public/status, and the brand
block on /public/settings (per-shard theming: name/accent/logo/hero/favicon).
- android/PLAN.md: mark §8 item 4 (version/health) and item 6 (branding) DONE and
update the prerequisite-progress summary — all v1 prerequisites are now done;
only push notifications (item 3) remains and is post-v1 (M7). App M0–M4 unblocked.
