Второй разъём у AD936x-плат — это второй КАНАЛ чипа (не порт B первого), и в
1R1T-образе он выбирается мультиплексором AD9361: debug-параметры
adi,1rx-1tx-mode-use-rx-num/-tx-num + биты RX1/RX2, TX1/TX2 регистров 0x3/0x2
(как switch_rfinput.sh/switch_rfoutput.sh прошивки). rf_port_select тут ни при
чём — прошивка его к тому же блокирует.
- IIOBindings: debug-атрибуты + прямой доступ к регистрам.
- PlutoBackend: детект второго разъёма (2R2T-каналы либо мультиплексор + модель
платы), SetAntPorts(RxPort,TxPort), ApplyRxMux/ApplyTxMux; Caps.HasAntSwitch.
⚠ApplyGain(Force): драйвер пропускает запись gain_control_mode, если считает
режим неизменным, — а у нового канала AGC-регистры не запрограммированы (в
железе крутится auto-AGC, hardwaregain отвергается EOPNOTSUPP). Форсируем
перепрог через другой режим после смены разъёма и после ad9361_set_bb_rate.
- RadioBackend: TBackendCaps.HasAntSwitch + virtual SetAntPorts (HPSDR — no-op,
там антеннами рулит Alex).
- Settings: секция ant936x (разъём RX/TX на диапазон и на слот трансвертера);
hw-AGC (режим + manual gain) переехал в TBandSettings/TXvtrEntry — теперь он
свой на каждом диапазоне и трансвертере.
- RadioController: FAnt936x + ApplyAntPorts (RestoreBand/ActivateXvtr/
StartRunning); ApplyBandDSP восстанавливает hw-AGC диапазона.
- SettingsForm: вкладка Antenna — Alex-таблица (openHPSDR) либо таблица
разъёмов AD936x по диапазонам/трансвертерам.

- Status bar / web now show Pluto/LibreSDR model + serial instead of
"Unknown Board" (BoardDisplayName in controller; UI just renders it).
- Field 3 shows AD936x chip temperature + RX RSSI for Pluto (no PA →
Supply only for openHPSDR). Polled via backend.ReadTelemetry (~2 Hz),
filtered for sensor glitches (plausibility window + slew-limit, with
anti-stick) — fixes rare bogus -15°C readings.
- Add libiio binding iio_channel_attr_read_double.
- Remove stale root pluto_integration.MD (superseded by
doc/PLUTO_INTEGRATION_PLAN.md).

- RX hw-gain (Pluto/AD936x): backend SetRxGain(ModeIdx, GainDb) — gain_control_mode
(manual/fast_attack/slow_attack/hybrid) + hardwaregain. Controller FRxGainMode/
FRxGainDb, commands SetRxGainMode/SetRxGain/RxGainBy, rfRxGain event, snapshot,
applied in StartRunning. Persisted per-device (rx_gain_mode/rx_gain_db). HPSDR
unaffected (backend no-op).
- UI: separate "RF AGC" panel below the (unchanged) WDSP AGC block, shown only for
Pluto — FAST/SLOW/HYB/MAN mode buttons + manual GAIN slider. LayoutLeftPanel
reflows lower panels via RelayoutBelowBands; no layout shift on HPSDR.
- Cold-init fix: direct sampling_frequency write doesn't load the AD9361 FIR
decimation filter, so a cold-booted Pluto showed a wide centre spike that didn't
track tuning (worked only after SDR Console pre-initialised it). Add optional
libad9361 binding (dynamic) and call ad9361_set_bb_rate() in ApplySampleRate,
which configures BBPLL + loads the FIR; falls back to direct write if absent.

Add ADALM-Pluto / AD9361 support as a second hardware backend alongside
openHPSDR, sharing the WDSP DSP pipeline and the existing controller API
(UI stays decoupled from logic).
- RadioBackend.pas: abstract TRadioBackend + TBackendCaps + TRadioDevice
(Kind/URI/Serial). THPSDRNetwork now derives from it (state via virtual
getters); TRadioController.FNetwork is the base type.
- IIOBindings.pas: dynamic libiio loader (runs without libiio present).
- PlutoBackend.pas: scan/probe-by-URI, connect, LO/rate/bandwidth/gain
control, RX streaming thread (int16->24bit BE -> OnDDCIQ), Q conjugated
to match WDSP IQ convention. Verified on LibreSDR (AD9361) over network.
- Unified discovery: TDiscoverThread scans both backends; network Plutos
found via direct ProbeURI (no mDNS needed). ConnectDevice dispatches by
Dev.Kind (EnsureBackend swaps backend, preserving callbacks).
- DeviceStore/DeviceForm: persist Kind/URI/Serial; save Pluto via
AddSavedPluto so saved/autostart devices reconnect across restarts.
- VHF/UHF band plan (BoardUtils, kind-aware): 6m..ADS-B for Pluto; fixes
HF clamps (band detect, mouse-wheel 60 MHz cap, freq-display max).
- SampleRateOverlay: configurable presets (Pluto 576k..5760k, >520 ksps),
auto-width to fit.
