Subject: [PATCH] fix(kiosk): add missing os_update import + guard Option<UCM>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. ui.rs lacked `use crate::os_update` — module declared in main.rs
   but ui.rs couldn't resolve os_update::check/apply calls.
2. webkit6::WebView::user_content_manager() returns Option<UCM> not
   UCM directly — guard with if-let instead of calling method on Option.
