* Refactor test fixtures and imports for optimization
- Reordered and optimized imports in `conftest.py`.
- Changed return statements to yield in `basic_graph` and `create_webhook` fixtures for better resource management.
- Added cleanup step to `create_webhook` fixture to delete created webhook after test completion.
* Refactor imports and add placeholder client fixture in test_ChatOllama_component.py
* Add pytest fixture 'client' to test_graph.py
* Add pytest fixture 'client' to test_callback_graph.py for test optimization
* Add 'unit_tests_looponfail' target to Makefile for running unit tests with loop-on-fail option

* refactor: move test_graph.py
* refactor: allow Graph to be initialized with no nodes and edges
The Graph class in `base.py` was refactored to separate the initialization of nodes and edges into a separate method called `add_nodes_and_edges()`. This improves code readability and maintainability by organizing the code logic more effectively.
* refactor: separate initialization of nodes and edges in get_graph()
The `get_graph()` function in `conftest.py` was refactored to separate the initialization of nodes and edges. This improves code readability and maintainability by organizing the code logic more effectively.
* refactor: separate initialization of nodes and edges in test_graph.py
* refactor: separate initialization of nodes and edges in base.py
The `add_node()` and `add_edge()` methods were added to the `Graph` class in `base.py` to separate the initialization of nodes and edges. This improves code readability and maintainability by organizing the code logic more effectively.
* refactor: move tests folder to src/backend
* chore(Makefile): update pytest commands to run tests from the correct directory paths for unit and integration tests
* refactor: update file path in test_custom_component.py
The file path in the test_custom_component.py file has been updated to use the correct relative path to the component_multiple_outputs.py file. This change ensures that the test code can access the correct file and improves the reliability of the test.
