pager: fix LR1121 TX power default and RX-boosted-gain gating

Browse Source 
Boot TX power was left at a conservative 10dBm (Heltec V4's pattern) with
no way to raise it, unlike the T-Deck which boots straight at the chip's
real 22dBm ceiling. On hardware this was silently degrading outbound
range: adverts/DMs sent from the pager were unreliable while inbound
reception was fine, since the far node's own TX power was unaffected.
22dBm is confirmed as this chip's actual sub-GHz HP-PA ceiling via
RadioLib's LR1120::checkOutputPower() (LR1121 inherits it) and matches
trail-mate's own working config for this board.

Also widen the three RX-boosted-gain gates in MyMesh.cpp/DataStore.cpp
that only checked USE_SX1262/USE_SX1268 to include USE_LR1121 --
CustomLR1121Wrapper already implements setRxBoostedGainMode/
getRxBoostedGainMode, so the setting was silently a no-op for this radio.
