Refactor imports and remove unused ActionOrder implementation

- Cleaned up imports across multiple modules for better organization and removed unused dependencies.
- Eliminated `ActionOrder` implementation from `executors` as it's no longer being utilized.
- Simplified error handling in `get_dependencies` using `unwrap_or_else`.
- Optimized test setups with consistent use of `tempdir` helper function.
