 * Last Modified: 2025-10-27
 * Description: Concrete implementation of IPurchaseService providing comprehensive purchase and monetization business logic operations including anti-pay-to-win monitoring, ethical VIP progression, spending balance validation, and skill-based alternative systems with player protection
 * Last Edit Notes: Fixed all compilation errors - added missing helper methods, corrected async/await usage, fixed enum casting, and implemented all missing functionality
