Pinia store used outside setup or without active instance

\[pinia\].*store.*already.*disposed|getActivePinia.*was called with no active Pinia

Fixes

1.Call useStore() inside setup() or a composable called from setup()
2.Ensure createPinia() is installed on the app before using stores
3.For usage outside components, pass the pinia instance: useStore(pinia)
