Refactor LibraryDebugCollector and TelegramApi for improved data handling and clarity
Updated the LibraryDebugCollector to introduce a new CompositionEntry record for better organization of group composition data. Refactored the composition logic to utilize this new structure, enhancing readability and maintainability. In the TelegramApi, replaced inline allowed_updates array with a static readonly field to reduce redundancy and improve clarity in API call configurations. Adjusted related tests to ensure proper handling of message assertions, enhancing overall test reliability.
