Add audio file upload support

* Refactor post_prompt function to include prompt_id handling

- Updated the post_prompt function in custom_routes.py to retrieve and validate a prompt_id from the incoming JSON data, defaulting to a new UUID if not provided.
- Adjusted the validation call to use prompt_id alongside the prompt, ensuring proper identification and processing of prompts.

These changes enhance the functionality of prompt handling within the application.

* Refactor post_prompt and send_prompt functions for async handling

- Updated the post_prompt function to be asynchronous, allowing for non-blocking execution when validating prompts.
- Adjusted calls to post_prompt in send_prompt and comfy_deploy_run to await the asynchronous execution, ensuring proper handling of prompt submissions.
- Commented out unused prompt construction code to streamline the function.

These changes enhance the performance and responsiveness of prompt handling in the application.

* Refactor handle_execute to support asynchronous execution

- Updated the swizzle_execute function to be asynchronous, allowing for non-blocking execution of the origin_execute function.
- Added missing parameters for pending_async_nodes in the swizzle_execute function call.
- Ensured that the result from origin_execute is awaited, improving the handling of asynchronous operations.

These changes enhance the performance and responsiveness of the execution handling in the application.

* Enhance error handling in post_prompt and origin_execute functions

- Added try-except blocks in post_prompt to handle TypeErrors during prompt validation, allowing for fallback to an older signature.
- Implemented similar error handling in the origin_execute function to manage potential TypeErrors, ensuring robust execution flow.
- Improved logging to capture issues with function signatures, aiding in debugging.

These changes improve the resilience of the application when dealing with prompt and execution validation.

* Refactor post_prompt and origin_execute for synchronous handling

- Modified the post_prompt function to call validate_prompt synchronously when a TypeError occurs, improving error handling.
- Updated the origin_execute function to execute synchronously, ensuring consistent behavior during execution.

These changes enhance the robustness of prompt validation and execution processes in the application.

* tweak: optional

* Refactor swizzle_execute for async and sync handling

- Enhanced the swizzle_execute function to differentiate between asynchronous and synchronous execution paths based on the origin_execute function's nature.
- Improved the structure of the swizzle_execute function to ensure proper handling of parameters and execution flow for both async and sync scenarios.
- Maintained existing error handling while ensuring consistent behavior across execution types.

These changes improve the flexibility and robustness of the execution handling in the application.
