refactor(iot-hub): move installed-item delete API call into the delete dialog

Push the deleteInstalledItem call from IotHubActionsService into the dialog's confirm() handler so the dialog itself manages its lifetime. Pass installedItemId in the dialog data and have confirm() fire the API call, then close with true on success. Drop the now-unused isLoading flips in the installed-items table since loading state is no longer optimistically toggled around the dialog.
