feat(legacy): add pull-to-refresh for control_panel and location

Introduce a shared RefreshableErrorState widget that wraps the retry
hint in a RefreshIndicator with an explicit 'pull down to retry'
caption, so users can recover from load failures without navigating
away. Wire it into the location screen's error fallbacks and make the
control_panel body pull-to-refresh at any time, invalidating the device
list so the dashboard picks up fresh data.
