fix(layout): refresh load() data on tab/app resume

Tauri WebView sessions (and long-lived browser tabs) persist
hydrated load() data indefinitely, so server-side changes never
surface until the user manually navigates across a depends()
boundary. Wire visibilitychange + focus to invalidateAll(),
throttled to once per 5 min to keep expensive loaders cheap.
