+ * @returns An object containing:
+ *   - `role`: The user's role, either "admin" or "user".
+ *   - `isAuthorized`: A boolean indicating whether the token is valid.
+ *
+ * @remarks
+ * - Extracts the token from the `Authorization` header.
+ * - Decodes and verifies the token using `jwt.verify()`.
+ * - Fetches the user profile from the database using `userId` from the decoded token.
