* fix(settings): show daemon update failures
React Native web ignores Alert.alert, so failed remote updates reset to an enabled button without any user-visible explanation. Keep updater progress and failure as explicit rendered state, including the daemon's error, and cover the real browser-to-daemon failure path.
* test(settings): harden daemon update regression
* fix(settings): disable Desktop-managed daemon updates
Desktop-bundled daemons advertised npm self-update even though the install-origin checks always rejected it. Report Desktop ownership to clients, render actionable guidance, and refuse stale requests before touching npm.
