This commit adds a new function `cascade_delete_flow` to the `utils.py` file in the `langflow.api` module. This function is responsible for deleting related records when a flow is deleted. It uses the `delete` method from SQLAlchemy to delete records from the `TransactionTable` and `VertexBuildTable` tables based on the flow ID. Finally, it deletes the flow record itself from the `Flow` table. The function is wrapped in a try-except block to handle any exceptions that may occur during the deletion process. If an exception is raised, a `RuntimeError` is raised with an appropriate error message. This refactor improves the code by encapsulating the cascade delete logic in a separate function, making it more modular and easier to maintain.

This pull request introduces a cascade delete function to address an issue where deleting a flow would sometimes fail due to related transactions and builds not being properly removed. The new function ensures that all associated transactions and builds of a flow are deleted before the flow itself is removed. This resolves errors that occurred when attempting to delete folders containing flows.
