This change follows the pattern of our cookies persistence implementation: the "browser" process is responsible for interacting with the sqlite database, and WebContent communicates all storage operations via IPC. The new database table uses (storage_endpoint, storage_key, bottle_key) as the primary key. This design follows concepts from the https://storage.spec.whatwg.org/ and is intended to support reuse of the persistence layer for other APIs (e.g., CacheStorage, IndexedDB). For now, `storage_endpoint` is always "localStorage", `storage_key` is the website's origin, and `bottle_key` is the name of the localStorage key.
