Hygiene: digit-terminate all generated refdeses — clears kicad-cli annotation errors

Browse Source 
33 component refs (J_E->J_E1, C_VCAP->C_VCAP1, C_IN5a->C_IN5a1, ...) plus 8
power-symbol refs (#FLG15IN->#FLG15IN1, #PWRC_E1g->#PWRC_E1g1, ...) now end
in a digit; emit helpers normalize tags so future sheets stay clean.
kicad-cli netlist annotation warning GONE. ERC 133->133 identical types;
analyzer +73/-4/~0 unchanged; SPICE 24 pass / 2 benign warn / 0 fail.
