Fix: Improve Edge session cleanup to prevent resource leaks In unstable network environments, Edge devices may frequently disconnect and reconnect. The previous session cleanup logic could fail to stop the Kafka consumer, creating a 'zombie consumer'. This commit introduces a multi-layered defense: 1. Proactively evicts stale members from the Kafka consumer group upon new connection to ensure immediate functionality. 2. Adds a background task to persistently try and clean up session objects that failed to destroy, preventing memory/thread leaks.
