refactor: streamline Redis caching logic across services

- Implemented a unified `getAndSet` method in RedisService to handle caching for single, list, and paginated responses.
- Removed redundant cache checks and writes in various services, simplifying the code and improving readability.
- Updated GoodsService, StockKeepingUnitsService, PartnerActivatedLicensesService, and others to utilize the new caching mechanism.
- Adjusted Prisma connection limit for better resource management.
