 * Service class for managing notification settings in the StudioCMS SDK.
 *
 * @remarks
 * This class provides methods to retrieve and update site-wide notification settings
 * from the database. If settings do not exist, default values are inserted.
 * All database operations are wrapped with error handling for `LibSQLDatabaseError`.
 *
 * @example
 * ```typescript
 * const settings = await SDKCore_NotificationSettings.site.get();
 * await SDKCore_NotificationSettings.site.update({ ...newSettings });
 * ```
 *
 * @service
 * @module studiocms/sdk/SDKCore/modules/notificationSettings
 *
 * @dependencies
 * - AstroDB.Default
 *
 * @effect
 * - genLogger for logging effect operations
 *
 * @throws SDKCoreError when a database error occurs
