feat(canvas): breadboards always sit behind everything 

A breadboard is the physical base of a circuit — boards, components and
wires all plug into it — so it should never cover them. Pin its group at
z-index -1 (below boards z 0, components z 1/2, wires z 35), ignoring
selection. Detected by metadataId prefix 'breadboard' (breadboard,
breadboard-mini). Its own pins stay wireable wherever it's not covered.
