docs: bump README to v1.9.7, document player list kick

When creating a session with an image, send it as a single SendPhoto
with the schedule text as caption (+ reply markup), instead of two
separate messages. Falls back to two messages if caption exceeds
Telegram's 1024-char limit.

Also adds BatchMessageEditor helper that transparently handles
EditMessageText vs EditMessageCaption depending on whether the batch
message is a text or photo message. Updated all handlers and web
service to use this helper.

Version bump to 1.9.7.

 ### 🤖 Telegram Бот
 - **📅 Создание расписаний (Batch Sessions)**: Создавайте сразу несколько игр одним сообщением (на неделю или месяц вперед).
+- **🖼 Обложки расписаний**: К batch-посту можно прикрепить фото к `/newsession` или указать строку `Картинка: https://...`; бот отправит обложку перед сообщением записи.
 - **⚡ Быстрые повторы расписания**: Для регулярной кампании можно указать одну дату, количество игр и интервал, а бот сам развернёт повторяющийся batch.
 - **✋ Интерактивная запись и выход**: Игроки записываются на конкретные даты и самостоятельно снимают запись нажатием одной кнопки.
 - **👥 Лимит мест и лист ожидания**: ГМ задаёт максимальный состав, бот не переполняет сессию, автоматически ведёт очередь ожидания и освобождённое место отдаёт первому ожидающему.
 - **📁 Поддержка Форумов (Telegram Topics)**: Бот автоматически создает тему во вложенных чатах Telegram под каждую новую пачку игр.
-- **❌ Управление сессиями**: Owner и назначенные co-GM могут создавать, отменять, удалять и переносить игры прямо из Telegram.
+- **❌ Управление сессиями**: Owner и назначенные co-GM могут создавать, отменять, удалять и переносить игры из Telegram через `/listsessions`; публичный пост записи показывает только кнопки игроков.
 - **🔄 Голосование за перенос**: При переносе сессии GM предлагает 2-3 новых времени и дедлайн, игроки голосуют кнопками, а бот показывает текущие результаты и применяет победивший вариант.
 - **🔔 Персональные уведомления**: Игроки получают DM о RSVP за 24 часа, напоминание за 1 час, ссылку перед игрой, отмены и переносы; групповые уведомления при этом остаются.
 - **🗓 Экспорт в Календарь**: Генерация файла `.ics` для добавления всех игр в Google, Apple или Яндекс Календарь одной командой.

 ### 🌐 Web Dashboard (Blazor Server)
 - **🔐 Авторизация через Telegram**: Безопасный вход с использованием Telegram Login Widget (HMAC-SHA256 валидация).
+- **📱 Telegram Mini App Dashboard**: Мобильная версия dashboard открывается прямо из Telegram, проверяет WebApp `initData` на сервере и использует те же права owner/co-GM, что и обычный Web Dashboard. Если Mini App попадает в fallback-вход, Telegram Login Widget авторизует пользователя callback-запросом внутри текущего WebView, а интерфейс учитывает safe-area телефона и верхнюю панель Telegram.
 - **📝 Удобное редактирование**: Веб-интерфейс для детального редактирования сессий, изменения дат, названий и статусов.
 - **🤝 Co-GM и делегирование**: Owner группы назначает помощников по Telegram ID, а co-GM получает доступ к управлению расписанием в Telegram и Web Dashboard.
 - **📋 Шаблоны кампаний**: Owner и co-GM управляют типовыми параметрами кампаний в отдельной вкладке `Шаблоны`, а на странице группы запускают новый повторяющийся batch из выбранного шаблона.

+# Telegram Mini App Dashboard Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a Telegram Mini App mobile dashboard that reuses the existing Web Dashboard and validates Telegram WebApp `initData` on the server.
+
+**Architecture:** Extend `TelegramAuthService` for WebApp init data, add a `/miniapp` Blazor entry page plus `/auth/telegram-webapp` endpoint, and add bot entry points through an inline WebApp button and optional menu button setup. Existing application/domain services remain the only write path.
+
+**Tech Stack:** .NET 10, Blazor Server, Telegram.Bot, xUnit, Dapper/Npgsql-backed existing services.
+
+---
+
+### Task 1: Telegram WebApp Authentication
+
+**Files:**
+- Modify: `src/GmRelay.Web/Services/TelegramAuthService.cs`
+- Modify: `src/GmRelay.Web/Program.cs`
+- Test: `tests/GmRelay.Bot.Tests/Web/TelegramAuthServiceTests.cs`
+
+- [ ] Write failing tests for valid WebApp `initData`, tampered hash, and expired auth date.
+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter TelegramAuthServiceTests`.
+- [ ] Implement WebApp HMAC verification using the Telegram `WebAppData` secret derivation.
+- [ ] Add `/auth/telegram-webapp` endpoint that signs in using the same claims as `/auth/telegram`.
+- [ ] Re-run the filtered tests.
+
+### Task 2: Mini App Entry Page
+
+**Files:**
+- Create: `src/GmRelay.Web/Components/Pages/MiniApp.razor`
+- Modify: `src/GmRelay.Web/Components/App.razor`
+- Modify: `src/GmRelay.Web/wwwroot/app.css`
+- Test: `tests/GmRelay.Bot.Tests/Web/MiniAppDashboardTests.cs`
+
+- [ ] Write failing tests that assert `/miniapp`, `telegram-web-app.js`, `authenticateTelegramMiniApp`, and Mini App CSS hooks exist.
+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter MiniAppDashboardTests`.
+- [ ] Implement `/miniapp` to post `Telegram.WebApp.initData` to `/auth/telegram-webapp`, expand/ready the Mini App, and show fallback login when opened outside Telegram.
+- [ ] Add CSS for a mobile-first Mini App shell and compact dashboard spacing.
+- [ ] Re-run the filtered tests.
+
+### Task 3: Bot Entry Points
+
+**Files:**
+- Create: `src/GmRelay.Bot/Infrastructure/Telegram/TelegramMiniAppMenuButtonService.cs`
+- Modify: `src/GmRelay.Bot/Infrastructure/Telegram/UpdateRouter.cs`
+- Modify: `src/GmRelay.Bot/Program.cs`
+- Test: `tests/GmRelay.Bot.Tests/Infrastructure/Telegram/TelegramMiniAppEntryPointTests.cs`
+
+- [ ] Write failing tests that assert `/start` exposes a WebApp button and startup registers the menu button service.
+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter TelegramMiniAppEntryPointTests`.
+- [ ] Add a configurable `Telegram:MiniAppUrl` entry point; when missing, keep existing command behavior.
+- [ ] Add hosted service that calls `SetChatMenuButton` with `MenuButtonWebApp` only when the URL is configured.
+- [ ] Re-run the filtered tests.
+
+### Task 4: Docs, Versions, and Release Prep
+
+**Files:**
+- Modify: `Directory.Build.props`
+- Modify: `compose.yaml`
+- Modify: `.gitea/workflows/deploy.yml`
+- Modify: `src/GmRelay.Web/wwwroot/app.css`
+- Modify: `src/GmRelay.Web/Components/Layout/NavMenu.razor`
+- Modify: `README.md`
+- Wiki: `Home`, `Быстрый старт`, `Руководство ГМа`, `Развёртывание`, `Архитектура`, `Разработка`
+
+- [ ] Update project/container/workflow/UI versions to `1.9.0`.
+- [ ] Document `TELEGRAM_MINI_APP_URL`, BotFather `/setmenubutton`, `/miniapp`, and WebApp auth.
+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --collect:"XPlat Code Coverage"`.
+- [ ] Run `dotnet build GM-Relay.slnx -c Release`.

+# Telegram Mini App Dashboard Design
+
+## Goal
+
+Issue #17 adds a Telegram Mini App dashboard as the mobile entry point for the existing Web Dashboard. Owner and co-GM users must be able to open the dashboard from Telegram, pass server-side Telegram WebApp `initData` validation, and manage only their own groups.
+
+## Scope
+
+- Add Mini App authentication using Telegram WebApp `initData`.
+- Add a `/miniapp` entry page that signs the user into the existing cookie auth flow, then opens the regular dashboard UI in mobile-first mode.
+- Reuse `AuthorizedSessionService`, `SessionService`, and existing Blazor pages for groups, sessions, templates, waitlist promotion, edit forms, and bulk batch operations.
+- Add bot entry points: a Mini App button in `/start` and a configurable default menu button when `Telegram:MiniAppUrl` is set.
+- Update README, wiki, deployment config, and visible version strings to `1.9.0`.
+
+## Architecture
+
+The Mini App is not a second dashboard implementation. It is a Telegram-authenticated entrance into the existing Blazor dashboard. This keeps authorization, domain operations, Telegram message synchronization, and Web Dashboard behavior in one place.
+
+`TelegramAuthService` gains a second verification method for WebApp `initData`. The server accepts the raw URL-encoded init payload at `/auth/telegram-webapp`, verifies the Telegram HMAC with the bot token, extracts the user id/name from the embedded `user` JSON, and issues the same auth cookie as the login widget endpoint.
+
+`/miniapp` loads `telegram-web-app.js`, posts `window.Telegram.WebApp.initData` to the server endpoint, expands the WebApp viewport, and redirects to `/`. If a user opens `/miniapp` outside Telegram, the page shows the regular login fallback.
+
+## Data Flow
+
+1. User opens the Mini App from the bot menu button or `/start` inline button.
+2. Telegram injects `initData` into the WebApp JavaScript API.
+3. `/miniapp` posts `{ initData }` to `/auth/telegram-webapp`.
+4. The server verifies the WebApp signature and expiry.
+5. The server creates the same claims used by Telegram Login Widget.
+6. Existing Blazor pages load groups through `AuthorizedSessionService`.
+7. Any edit, waitlist, template, or batch action still goes through existing services and keeps Telegram messages synchronized.
+
+## Error Handling
+
+- Missing or invalid init data returns `401` and leaves the user on the Mini App page.
+- Expired auth data is rejected with the same 24-hour window used by the Login Widget.
+- A verified Telegram user with no owner/co-GM groups sees the existing empty dashboard state.
+- Direct navigation to a foreign group/session still redirects to `/access-denied` through existing authorization checks.
+
+## Testing
+
+- Unit tests cover valid and invalid WebApp `initData`.
+- File-level regression tests ensure `/miniapp`, `/auth/telegram-webapp`, Telegram WebApp script loading, bot Mini App button, menu button setup, and mobile Mini App CSS hooks remain present.
+- Existing `AuthorizedSessionServiceTests` continue covering owner/co-GM access behavior.
