feat: enhance Safew chat handling and testing

- Updated `GroupsFromUpdates` function to return the number of updates processed, improving the polling mechanism.
- Added a new test `TestGroupsFromUpdatesCallbackAndJoinRequest` to validate handling of callback queries and join requests.
- Introduced `safewAllowedUpdates` to specify allowed update types in the polling request, enhancing chat management.
- Implemented `ensureWebhookCleared` method to manage webhook state before polling, improving reliability.
