Subject: [PATCH] feat: optimize HikariCP connection pooling for database
 microservices

- Add HikariCP connection pool settings to User Service, Account Service, Fund Transfer Service, and Transaction Service
- Configure maximum-pool-size: 10, minimum-idle: 5 for optimal resource management
- Set idle-timeout: 300000ms, connection-timeout: 20000ms, max-lifetime: 1200000ms
- Improves database performance by managing connections more efficiently
