Persist a macOS-only preference for disabling wx content protection while keeping protection enabled by default. Add a Preferences checkbox that reuses IDC_DISABLE_SCREEN_PROTECTION and reapply the protection state after preference changes. Apply content-protection updates to all current top-level wx windows so changing the preference while a modal dialog is active does not leave the main frame or other windows with stale protection state.
