feat(radar,cw): transponder CW panel switches to the Morse Expert engine

Background: the transponder panel CW decoder (added by the upstream
fork author) used a lightweight Kotlin Bayesian engine (core/domain/cw,
kept untouched as a fallback). This change makes the panel use the
Morse Expert engine ported in 4.5.0, so both CW entry points share the
same decoder with a live waterfall.

Changes:
- New mini layout cw_panel_main.xml (waterfall 80dp + decoded text,
  status line hidden but ID kept for controller lookup)
- MainActivity.onCreate overload with applyImmersive flag; panel binds
  with false so the host window system bars are not touched
- CwDecoderPanel now embeds the mini layout via AndroidView and drives
  the MainActivity controller: start/stop/reset map to the engine,
  lifecycle follows panel expand (start) / collapse (release mic)
- radar module now depends on feature:cw (+ constraintlayout 2.2.1,
  same as cw) for layout + controller reuse
- What's new rewritten in EN/TR/ZH for this release only

Verified: :feature:radar:compileDebugKotlin and :app:compileDebugKotlin
BUILD SUCCESSFUL locally; check_strings.py OK (7 files, no bare
apostrophes).
