docs: record oneOfSeveralPixInt (increment 5) + update remaining-widget list

GAUGE_COMPOSITE.md + CLAUDE.md: add the OneOfSeveral/oneOfSeveralPixInt button-
lamp reconstruction to the done list; narrow the remaining widgets to map (radar
marquee), PlayerStatus, vehicleSubSystems, plus the follow-ups to make the
duck/searchlight buttons dynamic (extend the Mech table to 0x37 + a Searchlight
table).

 **Alternate route considered:** run original `btrel410.exe` under DOSBox — **blocked**: it needs the
 VPX/IG board DOSBox can't emulate; bypassing it = the shim work anyway.
