PurgeLoop used Sleep(5000) — Stop had to wait up to 5 seconds for the
purge thread to wake before it could proceed. Fix: add TEvent FStopEvent;
Stop signals it before waiting on threads so PurgeLoop exits immediately.
Also moved client Disconnect calls before WaitFor so all sockets are
unblocked in parallel rather than sequentially.

- 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

Add FRulerLastSpan to ruler cache — previously only FCenterFreq
and ActiveVfoFreq were tracked, so span changes left the ruler
showing stale frequency step marks.

- 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).
