…d printConfig Update getPref to traverse dotted compound paths of arbitrary depth (e.g. mqtt.map_report_settings.position_precision) and extract leaf values or intermediate submessages. Update printConfig to recursively collect nested message fields in choices for --get and --set. Add comprehensive unit tests for multi-level printConfig and getPref in snake_case and camelCase. Fixes meshtastic#978.

📝 WalkthroughWalkthroughThe configuration CLI now resolves dotted paths through nested configuration messages and lists nested leaf choices. The changes include support for snake_case and camelCase paths, plus tests for nested values, intermediate messages, and invalid paths. ChangesNested configuration paths

Reject paths through repeated message fields.
If a user requests remote_hardware.available_pins.gpio_pin after configuration loads, this loop accepts available_pins because it has a message descriptor. Later traversal accesses gpio_pin on a repeated-field container and raises AttributeError instead of showing the available choices. Reject descent when curr_desc is repeated, but continue to allow a request for remote_hardware.available_pins itself. The generated schema defines available_pins as repeated.
