feat: Refactor Docker orchestrator and enhance test utilities

This commit includes a major refactoring of the Docker orchestrator implementation
along with improvements to the testing infrastructure:

- Refactored Docker orchestrator to handle dynamic port assignment
- Added comprehensive test utilities in docker-test-utils.ts
- Improved error handling and resource cleanup in test environments
- Enhanced NodeStatus interface with containerId and networkId
- Added support for different storage types in NodeConfig
- Fixed request port handling in TestOrchestrator
- Added proper cleanup method to NodeOrchestrator interface

The changes ensure more reliable container management and better test isolation
while maintaining backward compatibility with existing implementations.

BREAKING CHANGE: The NodeOrchestrator interface now requires a cleanup() method.
