The Android app's embedded push distributor (M7 Part 2) needs the shard's
client-facing ntfy relay URL to build its device topic endpoint, but the M7
Part 1 backend only used the NTFY_* vars server-side and never surfaced them.
Add a `push: { ntfyUrl }` block to settings.getPublic(), sourced from
NTFY_PUBLIC_URL or the first NTFY_ALLOWED_ORIGINS entry (never the possibly
internal NTFY_BASE_URL); null when unconfigured, so the app shows push as
unavailable for that shard. Additive, non-sensitive, forward-compatible.
- Extend the PublicSettings swagger schema; regenerate swagger-output.json.
- publicBrand.test.js: cover null / NTFY_PUBLIC_URL / NTFY_ALLOWED_ORIGINS.
- Document NTFY_PUBLIC_URL in .env.example and (docs PR) BACKEND_DESIGN.md.
Full server suite green (250 pass).

Branding is already returned by GET /public/settings (the `brand` block:
name/colors/logo/hero/favicon, per-shard from BRAND_*). §8.6 of the Android
plan asks to confirm it — this makes it a first-class part of the contract so
the app's OpenAPI codegen produces typed branding instead of an untyped map.
- Swagger: add Brand + PublicSettings schemas; /public/settings now references
PublicSettings (was additionalProperties:true). Brand documents that asset
fields may be site-relative paths (resolve against the base URL).
- test/publicBrand.test.js locks the brand theming contract the app depends on
(all fields present; BRAND_* defaults; admin site_title/contact_email
overrides; accentInt never leaked).
No behavior change to the response — it already carried `brand`; this types and
guards it.
