Add telegram_communication app with dedicated DB routing

- Register TelegramCommunicationConfig in INSTALLED_APPS and add telegram_db to DATABASES
- Define TelegramData model mapped to the messages table
- Fix allow_migrate in ProjectDatabaseRouter: redirect and telegram entries were returning the DB name string (always truthy) instead of a boolean comparison, causing their migrations to bleed into every database
- Add telegram routing to db_for_read, db_for_write, allow_relation, and allow_migrate
