Add show_wire_loops option to suppress cable self-loop edges

Browse Source 
Cable self-loop edges (W1:e → W1:w) arc over the cable table to show
internal wire routing, but add visual noise on straight-through
harnesses. New Options field defaults to True for backward compat.

Usage:
  options:
    show_wire_loops: false
