Completes the FEM RX-gain restoration begun in the CAD/prefs change, which
persisted radio_fem_rxgain but didn't yet drive the hardware. Also dropped
by the 22eb9b87 revert; restored to match upstream.
- MainBoard: setLoRaFemLnaEnabled()/canControlLoRaFemLna()/isLoRaFemLnaEnabled()
virtuals (default: can't control — non-FEM boards report unsupported)
- heltec_v4: board overrides driving loRaFEMControl; LoRaFEMControl gains the
isLNAEnabled() getter (it already tracked lna_enabled and drove the FEM)
- CLI: `set radio.fem.rxgain on/off` / `get radio.fem.rxgain` (guarded by
canControlLoRaFemLna, so it reports "unsupported" on non-FEM boards)
- app startup applies the persisted pref: board.setLoRaFemLnaEnabled(
_prefs.radio_fem_rxgain), beside setRxBoostedGainMode
Default is ON (upstream), so on FEM boards the LNA is enabled after upgrade —
a real reception behavior change to confirm on hardware. The other FEM
variants (heltec_t096/tower_v2/tracker_v2) need the same small board-override
addition; until then `radio.fem.rxgain` reports unsupported there (no
regression — status quo).
Builds: heltec_v4 repeater-observer + room-observer (FEM board), Heltec_v3
repeater (non-FEM, base virtuals no-op). NEEDS on-device validation on a
Heltec V4.
