feat(cw): wire CW decoder page into navigation (between Roaming and Map)

Compose integration of the ported CW decoder engine:
- CwDecodeScreen: AndroidView embedding the ported activity_main.xml,
  lifecycle delegated to the ported MainActivity controller (onCreate ->
  onResume, onDispose -> onPause/onDestroy), RECORD_AUDIO runtime
  permission flow (with permanent-denial -> app settings), original
  options_menu actions as a top button row (pause/clear/save/record/
  settings), double-back-to-exit preserved
- CwSettingsDialog: message_type (general_text/ham_radio_qso),
  text_font_size (7-99), and the 9 color keys (bg_color/text_color/...)
  reading/writing the same prefs keys as the original app
  (getPackageName()+"_preferences"), colors sourced from I2.b tables
- Navigation: Screen.CwDecode ("CwDecode") placed between Roaming and
  Map in the default order; defaultScreenOrder updated; ic_cw morse icon;
  nav_cw strings (en/zh/tr); app depends on :feature:cw

Verified: :feature:cw:compileDebugKotlin + :app:compileDebugKotlin
BUILD SUCCESSFUL (first pass, no errors).
