Enhance MQTT status message to include repeat status

Updated the MQTT message structure to add a new field for repeat status, allowing the indication of forwarding status as "on" or "off". This change includes modifications to the MQTTMessageBuilder and related documentation to reflect the new parameter. Additionally, updated CLI command documentation to clarify flooding behavior in different firmware versions.
