feat: auto-generate room names on message send

Introduces functionality to auto-generate and set room names for conversations that still have the default name upon sending a message. This leverages a new `generate_room_name` method that creates a room name based on the last few messages. Enhancements include better event handling with refined logging during event processing errors. This update aims to enrich room identification for users by providing more contextually relevant names, improving navigation and user experience in multi-room setups.
