PA PL1 re-targets the PA's DC-DC supply rail rather than selecting a logic-level gain, and the serial CLI is serviced on every main-loop pass regardless of whether a transmit is in flight. A `set radio.fem.txgain` write could therefore move the rail mid-transmit, while the SX1262 was still driving the PA at full input power. Record the requested level in setPAGainEnable() and drive the pin from setTxModeEnable(), which runs from onBeforeTransmit() ahead of startTransmit(). The level only matters while transmitting, so deferring costs nothing. Document that the pref is saved immediately but applied at the next transmit, so `get radio.fem.txgain` can lead the hardware until then.
