- Extracted `safeLaunchLoad` inline extension function to `ViewModelExt.kt` to encapsulate API call success/failure handling logic and replaced usages across 18 viewmodels.
- Extracted `ToastHost` interface to standardize `clearToast()` behavior across all ViewModels displaying toasts.
- Extracted `ToastEffect` composable to `SharedComponents.kt` and applied it to 16 screens, reducing repetitive side effect code blocks.
Fixes#286
- HermesScaffold: added isRefreshing param, wraps content in PullToRefreshBox when onRefresh is set
- All 16 data screens: pass isRefreshing = state.isLoading
- Initial loading only shows full-screen LoadingState when data is empty (no spinner over existing content)
- AchievementsScreen already had the correct pattern, just needed isRefreshing param
