Replaces the custom-scheme auto-redirect (which triggers Chrome's
confirmation prompt) with a verified Android App Link handoff:
- public/.well-known/assetlinks.json for space.einundzwanzig.mobile
(debug cert fingerprint; add the release cert before store builds)
- GET /app/auth handoff: opens the app directly when the App Link is
verified; renders a button-based fallback page otherwise
- POST /api/mobile/token: trades a NIP-55-signed login event for a
Sanctum token — used when Amber's callback opens the app directly
- complete/confirm/signedCallback now redirect to the handoff URL
Amber drops the query string when it rebuilds the callback URL and
appends the signed event directly to the path. The mobile login page now
hands out path-based callback URLs (/auth/mobile/signed/{k1}/) so the
event arrives as the remainder of the path.
The new callback runs in the web middleware group: the signer opens it
in the system browser, which shares cookies with the in-app browser
session, so the flow completes immediately — a bridge page issues the
token and fires the einundzwanzig:// deep link. The LoginKey row is
still written as a fallback for the polling login page.
The Einundzwanzig mobile app opens /auth/mobile in an in-app browser.
After a Lightning (LNURL) or Nostr login the flow issues a personal
access token and hands it back via the einundzwanzig://auth deep link.
- New auth.mobile-login Livewire view: Lightning QR (shared k1) plus
Nostr signing via NIP-55 Android signers (Amber) with server callback,
and a confirmation screen for already authenticated sessions
- MobileAuthController: NIP-55 callback verification, completion route
issuing the token (replacing same-device tokens), redirect whitelist
- Nostr login event verification and npub user resolution extracted to
App\Support\NostrLogin, now shared with the interactive login
- GET /api/user (auth:sanctum) returns the token owner's profile
