Phase 1: extract TRadioController (state + engine ownership)

Browse Source

Decouple MainForm from CAT/Web by introducing a headless core,
TRadioController, as the single home for radio state and engine objects.
This is groundwork for swappable UIs, a daemon (Web-only) mode, and a
future hardware control panel — each becomes a frontend/adapter over the
same controller API.

RadioController.pas (new):
- Radio state + engine objects (Network/DSP/Audio/Settings/Channels) as
  public fields named exactly as in MainForm, so wiring is mechanical.
- Command API: absolute Set* plus relative *By/Up/Down (for encoders).
- OnStateChanged(field) notifications and GetSnapshot for frontend sync.
- Invoke/OnInvoke (TUIInvokeEvent) thread-marshalling seam (GUI uses
  TThread.Synchronize; daemon supplies its own).
- Commands are scaffolding for now (update field + fire event); engine
  logic stays in MainForm and migrates in later phases (TODO-wiring).

MainForm.pas:
- Owns FController; creates it first in FormCreate, frees it last in
  FormDestroy. Engines are still created/freed by MainForm into the
  controller's fields (ownership move is a later phase).
- ~1400 FXxx references redirected to FController.FXxx (implementation
  only); dead field declarations removed from the interface.

No behavioral change — pure state relocation. Builds clean (cocoa).
