feat: import Graph without position information (#3203)

* refactor: Add utility functions for getting handle IDs in CustomNodes

- Added `getRightHandleId` function to generate the right handle ID for source handles.
- Added `getLeftHandleId` function to generate the left handle ID for target handles.
- These functions improve code readability and maintainability by encapsulating the logic for generating handle IDs.

* refactor: Add loading module to __init__.py for improved organization of interface package

* refactor: Clean up imports in base.py and enforce edge validation in Graph class for improved maintainability and error handling

* refactor: Remove edge component additions in test_base.py to streamline graph tests and emphasize error handling for unprepared graphs

* refactor: Mark @clack/prompts is-unicode-supported as extraneous in package-lock.json for better dependency management

* refactor: Update dataType assignment in Component class to use component name if available, or fallback to class name

* refactor: Fix edge existence check in Graph class to use correct variable, ensuring accurate validation of graph structure
