[feat](trx-server): add configurable display name for rigs

Add optional `name` field to RigInstanceConfig to allow long-form rig names
(e.g., "HF Transceiver"). The name defaults to rig id if not configured.
Add display_name() method to get display name with fallback to id.
Propagate display_name through RigHandle to listener for GetRigs response.
