fix(device_parameters): walk connector host_parameters so host-side params are reachable

Browse source 
list_device_parameters and set_device_parameter only iterated
device.device_parameters and connector.parameters. Host-side parameter
sets -- e.g. the WAGO 750-series 'K-BUS Parameters' grid (program start
interlock, k-bus cycle time, TCM control) -- are exposed exclusively via
ScriptConnector.host_parameters (SP21 stub ScriptDeviceParameters.pyi;
helpme-codesys ScriptEngine, ScriptConnector.host_parameters), so both
tools reported zero parameters on the Kbus master node.

Verified on the Sea Leopard PFC200 project: id 150 'program start
interlock' now lists and sets offline.
