Add MongoDB Atlas support for TestContainers and Docker Compose

Implement service connection support for MongoDB Atlas using both
TestContainers and Docker Compose. This change enables easier
integration testing and local development with MongoDB Atlas.

- Leverage TestContainers 1.20.2 which introduces MongoDBAtlasLocalContainer
- Add TestContainers support using MongoDBAtlasLocalContainer
- Implement Docker Compose configuration for MongoDB Atlas
- Create connection details factories for both TestContainers and Docker Compose
- Update dependency management for MongoDB Atlas integration
- Add integration tests for both TestContainers and Docker Compose setups
- Update documentation to include MongoDB Atlas support
