False "suspect hardware" verdict on healthy BL1850B packs.

The on-device Debug screen showed "Latched: YES" and the verdict read SUSPECT on packs that are balanced, unlocked and working normally. The low-level BMS marker this relied on turned out to be a constant that these packs always carry, not a stored fault, so the tool was flagging good packs.

The marker no longer affects the verdict. A genuinely locked pack is still detected by its charger lock, and the Debug screen now shows the raw marker bytes for reference.
