- Subscribe to cosmic_config changes for com.system76.CosmicComp so active_layouts is refreshed whenever xkb_config changes at runtime (previously the locker cached active_layouts at startup and never updated, leaving the dropdown checkmark pointing at a stale layout). - Extract refresh_active_layouts() from update_user_data() and reuse it from the new XkbConfigChanged handler. - Show the active layout code (EN/RU/...) next to the keyboard icon on the lock screen so users don't have to open the dropdown to see which layout is currently active.

This PR stands on its own — any tool that changes
