Mechanical switches use pull-up only. PTT and charger active levels are retained
from the previous configuration and require actual idle/active measurements.
Battery full-charge prompts still use voltage/percentage/time inference rather
than GPIO8. ADC divider gain/offset remain unchanged pending VBAT measurements.
Battery charge/full state uses GPIO18/GPIO8 with 100ms polling and 1s sampled
stability confirmation. Both active means fault; both inactive means not charging.
Full prompts require a confirmed charging-to-full transition; no voltage inference. ADC divider gain/offset remain unchanged pending VBAT measurements.

Charge inputs are polled without GPIO interrupts. Low-active deep-sleep wake follows
`CONFIG_TQ_BATTERY_CHARGE_GPIO=18`; the full input is not a wake source. Verify charger insertion/removal and wake
behavior after changing the board.
