Add KiCad module carrier PCB draft

Browse Source 
Introduce an editable KiCad 10 schematic and routed two-layer 82 × 80 mm
layout with local provisional footprints, validation tooling, and
component
research. Keep the RS-232 male-module mapping and mechanical clearances
explicitly provisional pending hardware verification.
