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.

Introduce DeviceStore.pas (TDeviceStore) as the single source of truth for
saved devices (hpsdr_devices.ini CRUD + autostart) and the current discovery
list. The controller owns one instance (created/freed in its ctor/dtor);
desktop and (later) web frontends edit/render through it so the lists never
diverge.
Refactor TDeviceDialog to use a TDeviceStore reference instead of its own
arrays + ini code. MainForm wires FDeviceDialog.Store to the controller's
store, routes discovery results (DoAddDevice) and the preload-rate lookup
through it (TDiscoveredDevice now carries the MAC), and drops the now-unused
FDevices/TDeviceItem. Behavior-preserving for the desktop dialog.
