/**
 * @description
 * FieldTestPlugin provides comprehensive test cases for all custom field types and
 * configurable operation argument types supported by Vendure. This plugin is designed
 * specifically for development and testing purposes to validate the universal form
 * input system in the dashboard.
 *
 * ## Custom Fields Coverage
 * Tests all CustomFieldType values on the Product entity:
 * - string (with and without options, lists)
 * - localeString (translatable strings)
 * - text (long text fields)
 * - localeText (translatable long text)
 * - int (with min/max/step validation)
 * - float (with precision controls)
 * - boolean (single and list)
 * - datetime (dates and date lists)
 * - relation (single and multi-relation)
 * - struct (complex objects and lists)
 *
 * ## Configurable Operation Args Coverage
 * Tests all ConfigArgType values and DefaultFormComponentId components:
 * - All basic types: string, int, float, boolean, datetime, ID
 * - All UI components: text, password, textarea, number, currency, boolean,
 *   select, date, rich-text, json-editor
 * - Advanced features: lists, options, validation, prefixes/suffixes
 *
 * ## UI Features Tested
 * - Tab organization
 * - Full-width layouts
 * - Readonly fields
 * - Field validation (min/max/step)
 * - Select options and multi-select
 * - List field management
 * - Custom UI component integration
 *
 * ## Usage
 * 1. Add this plugin to your dev-config.ts plugins array
 * 2. Navigate to any Product detail page to see custom fields
 * 3. Go to Settings → Payment Methods → Add "Comprehensive Test Payment Handler"
 *    to see configurable operation arguments
 *
 * @docsCategory plugin
 * @since 3.4.0
