/**
 * @description
 * The SettingsStoreService provides a flexible settings storage system with support for
 * scoping, permissions, and validation. It allows plugins and the core system to
 * store and retrieve configuration data with fine-grained control over access and isolation.
 *
 * ## Usage
 *
 * Values are automatically scoped according to their field configuration:
 *
 * @example
 * ```ts
 * // In a service
 * const userTheme = await this.settingsStoreService.get('dashboard.theme', ctx);
 * await this.settingsStoreService.set('dashboard.theme', 'dark', ctx);
 *
 * // Get multiple values
 * const settings = await this.settingsStoreService.getMany([
 *   'dashboard.theme',
 *   'dashboard.tableFilters'
 * ], ctx);
 * ```
 *
 * @docsCategory services
 * @since 3.4.0
