Plan + client README updated for the guest Wahl result endpoint/tab, the
WebSocket chat wiring, and the ChatGateway caller-promise fix. Section 8
now scopes the remaining Flutter work to the Authentik-dependent screens.

# KC-App client (Flutter)
Single Flutter codebase for the KC-App platform. **Web** is the only target
enabled so far (`flutter config --enable-web`); Android/iOS/desktop can be
added later with `flutter create --platforms=...` in this directory — the
`lib/` code is platform-agnostic.
## Run
```bash
flutter pub get
flutter run -d chrome --dart-define=API_BASE=http://localhost:3000/api
```
`API_BASE` defaults to `http://localhost:3000/api` (the local NestJS
backend, which also serves the interim plain-HTML client at `/`).
## What's implemented
- **Login** (`lib/screens/login_screen.dart`) — three tabs:
- *Konfi / Gast*: KC invite code + first/last name → `POST /auth/guest`.
- *Team-Login*: email + password for local Gemeinde Teamer →
`POST /auth/team-login`. (Leitungsteam / Verantwortliche use the
Authentik Authorization-Code flow, not yet wired into this client.)
- *Einladung*: redeem a Teamer invite token → `POST /auth/teamer/register`.
- The token is stored via `shared_preferences` (localStorage on web) and
restored on start; `GET /auth/me` resolves the role for a role-aware home.
- **Home** (`lib/screens/home_screen.dart`) — identity card + navigation.
- **Workshop-Wahl** (`lib/screens/wahl_screen.dart`, guests) — two tabs:
*Wünsche* (`GET /wahl/guest/overview`, tap workshops in order, max 3,
`POST /wahl/:id/teilnehmer`) and *Ergebnis* (`GET /wahl/guest/results`
PENDING / ASSIGNED with workshop + wish rank / UNASSIGNED).
- **Dateien** (`lib/screens/files_screen.dart`) — `GET /files/:kcId`,
filtered server-side by the caller's visibility tier.
- **Chat** (`lib/screens/chat_screen.dart` + `lib/chat_socket.dart`) —
channel list, REST history, then a live `/chat` WebSocket connection
(`chat:join` / `chat:send` / `chat:message`) with a compose bar.
## Architecture
- `lib/api.dart``Api` (thin REST wrapper + models) and `AppState`
(`ChangeNotifier`: session, login/logout, token persistence).
- `lib/main.dart``AppScope` (an `InheritedNotifier<AppState>`) exposes
`AppScope.of(context)`; `_AuthGate` switches Login/Home. No third-party
state-management package.
