Telegram Mini App v1: initData auth bridge into the existing site

Browse Source

- POST /api/public/tg-webapp-auth: HMAC-verifies WebApp initData against the
  companion bot token (12h freshness, timing-safe), maps chat -> member via
  tg-links.json, mints a message session -> linked members land on /my/<id>
  with zero login
- /app entry page (vendored telegram-web-app.js keeps CSP script-src 'self');
  unlinked users get the one-time wallet-link instructions
- tg-app.js on all pages: no-op in browsers; inside the webview lazy-loads the
  SDK, expands, themes header/background #071421, wires native BackButton
- Bot menu button set programmatically to open /app; /start + help mention it
- Synced chat.js canned answer + AI system prompt (Mini App facts)
