Integrate Telegram bot with command support

Replaces the previous TelegramBots dependency with the new telegrambots-client, extensions, and longpolling modules. Adds StoreScrapeBot with command handling, including a stub AddGroupCommand, and updates Main to start the bot. Config is extended to support bot credentials and admin IDs, and CouchbaseUtil is simplified to remove example code.
