Protocol Appendix A documents only the ADC reference voltage constant;
the PCB voltage divider must also be applied (from Thetis source):
- Boards 1-3 (Hermes/Angelia): ×(4.7+0.82)/0.82 ≈ 6.73, Vref=3.3V
- Board 5 (Orion MkII): ×(22+1)/1.1 ≈ 20.9, Vref=5.0V
For board type 5, supply voltage is measured via UserADC0 (bytes 57-58),
not the supply_volts field (bytes 49-50), matching Thetis behaviour.

The emulator (and real hardware) creates ddc_specific_thread (port 1025),
duc_specific_thread (port 1026), and rx_thread[0..3] (ports 1035+) only
after receiving HP Run=1. Previously ConfigureDDCs and SendDUCSpecific
were sent before SetRunAndFreq(True), so both packets arrived at closed
ports and were silently dropped — ddcenable remained -1, rx_thread slept
forever, no IQ data ever arrived, and the 5-second timeout fired Run=0.
Fix: reorder DoConnectDevice to send Run=1 first, then DDC/DUC Specific.
Also add keepalive resend of the cached DDC Specific packet every 500 ms
for the first 5 seconds after start, to handle thread-startup races on
real hardware over the network.

Per Appendix A of openHPSDR Ethernet Protocol v4.3:
- Boards 1,2,3 (Hermes/Angelia): V = ADC/4095 * 3.3 (was always using this)
- Boards 4,5 (Orion/Orion MkII): V = ADC/4095 * 5.0 (was wrong, showing ~66% of real value)
- Board 0 (Atlas) has no supply voltage measurement per protocol spec
("not Atlas bus systems")
- Boards 6 (Hermes Lite), 10 (Saturn): constant not documented, hide Supply field
ADCToSupplyVolts now takes BoardType and returns -1.0 for unsupported boards.
DoUpdateStatus omits the Supply field when -1.0 is returned.

- Settings.pas: add root-level SaveCATSettings/LoadCATSettings so CAT
config is stored independently of device MAC.
- MainForm.pas FormCreate: initialize CAT defaults, load from saved
'cat' JSON section, and apply immediately after InitCATEngine — so
SettingsForm shows correct values before the transceiver connects.
- MainForm.pas OnCATSettingsChange: always save to root 'cat' section
(not only when device is connected) so changes persist immediately.
- Default TCP CAT port changed from 4992 to 19090 everywhere.

- Remove FillDemoSpectrum from FormCreate: spectrum no longer shows
fake signal data before the transceiver is connected.
- Add SaveStartupPreview to STOP path: startup.vfo_a now matches the
device band cache so the display is consistent before and after
clicking START on a fresh launch.

Save current band and global settings in the STOP path so the next
START restores the frequency the user was on, not the hardcoded default.

Three params were never synced to FSpecView after FormCreate:
- WDSPReady: now set every timer tick so the draw branch (real
WDSP thresh/hang vs. static AGCTop) is always correct
- AGCThresh/AGCHangLevel: synced from FDSPEngine after
UpdateAGCLines in SpectrumTimerTick
- AGCTop: synced in TrkAGCChange, RestoreBand and DoConnectDevice

- New unit SpectrumView.pas (TSpectrumView): encapsulates all
spectrum, waterfall, ruler and S-meter rendering; ~900 lines
removed from MainForm.pas
- Fix marker bug: FMarkerActive/FMarkerX were duplicated in
MainForm and TSpectrumView — mouse handlers now write directly
to FSpecView, stale MainForm fields removed
- Fix filter band and ruler not following VFO: add SyncSpecViewFreq
helper called at every draw site and at top of SpectrumTimerTick
- Remove dead code: WFALL_PALETTE (34 lines), FSplitter, LblAGC,
LblVol, WinFirewall/IntfGraphics/FPImage from uses
- Fix pre-existing bug: SidetoneFreqLo := 600 overflowed Byte,
replaced with Hi(600)/Lo(600)

New units: CATEngine (Kenwood + Thetis ZZ* commands), CATSerial
(up to 4 serial ports), CATTcp (multi-client TCP server on port 4992).
MainForm wired with TCATContext callbacks reusing existing WebOn* handlers.
SettingsForm gets a new CAT tab with 4 serial port groups and TCP section.
Settings.pas extended with CAT config fields (per-device, JSON-persisted).
