refactor(useStorageState): supports both type aliases and interface-defined object types within Serializable<T>

[frontend-jihyeok-um]

Overview

• When T is defined as an interface, TypeScript sometimes fails to recognize it as a subtype of Record<string, unknown>.
• As a result, Serializable becomes never, breaking type inference.
• Adds ToClosedObject to normalize interface types into concrete object types.
• Adds NotFunction to exclude function types from being treated as serializable.
• Broadens the allowed types so that both type aliases and interfaces are correctly inferred as serializable objects.

Checklist
