refactor(ui): Replace waitForState and shareLatest with lifecycle-aware state collection

Add collectAsStateWithLifecycle for all Compose state collection (except Glance widgets). Add asLiveState() extension to ViewModel2 as a simpler replacement for shareLatest(scope = vmScope). Remove custom waitForState helper and shareLatest utility.
