Fix QuotaExceededError

✅ Solution

`QuotaExceededError` in Firebase Auth often arises when browser storage (like localStorage or IndexedDB) used for persisting authentication state is full, especially with large user data or excessive caching. Fix this by reducing the data stored in localStorage/IndexedDB—clear unnecessary data periodically using `localStorage.removeItem()` or `indexedDB.deleteDatabase()`, and consider using shorter persistence times for authentication data with `firebase.auth().setPersistence()`.
