- 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.

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).
