fix(engine): enable take-from-foundation for restored and startup games

GameState serializes take_from_foundation=false (the core default),
so saved games on disk and direct-loaded states never had the setting
applied from SettingsResource — only freshly dealt games did.

Two fixes:
- sync_settings_to_game: new system that reads SettingsChangedEvent
  and patches game.0.take_from_foundation on every settings change
  (covers initial settings load at startup and in-session toggles)
- handle_restore_prompt: apply settings immediately after game.0 =
  restored so the Continue path also respects the current setting
- Register SettingsChangedEvent in GamePlugin::build (idempotent with
  SettingsPlugin) so the message is available in headless test apps
