feat(mqtt): add EastIdahoMesh preset and enhance CLI preset listing

Added the EastIdahoMesh preset to the MQTT bridge implementation, increasing the total number of built-in presets. Updated the CLI to support listing available MQTT presets with pagination, improving user experience when configuring MQTT connections. Adjusted related documentation to reflect these changes.
