- Added memory debugging features to log heap usage and fragmentation recovery for MQTT clients.
- Introduced `recreateMqttClientsForFragmentationRecovery()` to manage MQTT client lifecycles and reduce memory fragmentation.
- Updated critical memory checks to log detailed heap statistics and active MQTT client counts.
- Included new debug logging for memory status every 60 seconds when memory debugging is enabled.
This update aims to improve stability and performance in memory-constrained environments.
