Implement unified storage architecture
- Replace fragmented storage backends with single IndexedDBStorageBackend - Create multi-store StorageBackend interface (storeName parameter) - Remove old backends: IndexedDBBackend, LocalStorageBackend, SessionIndexedDBBackend, WebExtensionStorageBackend - Remove old repositories: ProviderKeysRepository, SessionRepository, SettingsRepository - Simplify AppStorage to directly expose storage methods (getSetting/setSetting, getProviderKey/setProviderKey) - Create SessionsRepository for session-specific operations - Update all consumers to use new simplified API - Update example app to use new storage architecture - Benefits: 10GB+ quota (vs 10MB chrome.storage), single database, consistent API
