Add configurable KiCad field export for part parameters

Add a kicad_export checkbox to parameters, allowing users to control
which specifications appear as fields in the KiCad HTTP library API.
Parameters with kicad_export enabled are included using their formatted
value, without overwriting hardcoded fields like description or Stock.
