fix(channels/telegram): migrate from telegraf to grammy

Replace Telegraf with Grammy as the Telegram Bot framework.

- Replace @telegraf/types with @grammyjs/types in package-lock.json
- Swap telegraf dependency for grammy ^1.41.1 in package.json
- Update TelegramAdapter.ts: Bot instead of Telegraf, .api.* instead
  of .telegram.* calls, .start() instead of .launch(), adjusted event
  subscription syntax (message:text, message:photo, message:document)

Grammy is a more modern and actively maintained Telegram bot framework
for Node.js, improving reliability and reduce legacy dependencies.
