fix: make chat input sorting logic exclude other components (#5760)

* fix: Adjust chat input handling in layer sorting logic

* fix: Update chat input sorting logic and assertions in tests

* [autofix.ci] apply automated fixes

* fix: Update test assertion for chat input sorting to reflect changes in expected output

* [autofix.ci] apply automated fixes

* fix: update vertex sorting logic to handle start_component_id condition

- Modified the condition for sorting layers to include a check for start_component_id being None, ensuring correct behavior when this parameter is not set.
- This change improves the accuracy of the vertex sorting process in the graph utility functions.

* fix: update test assertion for vertex IDs in test_get_vertices

- Modified the test assertion in `test_get_vertices` to reflect the expected output, ensuring it only checks for "ChatInput" in the returned IDs.
- This change improves the accuracy of the test by aligning it with the current expected behavior of the endpoint.
