Refactor RolePlay application structure and enhance configuration

- Remove the RolePlayApplication class as part of the restructuring.
- Update pom.xml to include new dependencies for YAML configuration and H2 database support.
- Modify API package imports in ModelResource, SessionResource, and TurnResource to use the generated API package.
- Update application.yml to configure H2 datasource and enable Liquibase migrations at startup.
