(feat) Add support for Hikari Datasource

[rakhiagr]

Summary

This pull request introduces support for the HikariCP connection pool in the Ebean DAO implementation. The most significant changes are the addition of the HikariCP dependency and logic to handle HikariCP data sources when creating the schema evolution manager configuration.

Dependency management:

• Added externalDependency.hikariCP to the dao-impl/ebean-dao/build.gradle dependencies to enable HikariCP support.

Schema evolution manager initialization:

• Updated EbeanLocalAccess.java to import HikariDataSource for type checking and extraction of connection details.
• Modified the createSchemaEvolutionManager method in EbeanLocalAccess.java to detect if the Ebean server is using a HikariCP data source and extract the JDBC URL, username, and password accordingly. Falls back to the existing logic if HikariCP is not used.

Testing Done

./gradlew build
