NameError: name 'Union' is not defined

To Reproduce

1. Get code from master (sha: 4b54d93744e680a94bb0fda581f76fe5d28fc8a5)
2. Run command python main.py -sv -u 'user' -p 'pass'
3. Build fails NameError: name 'Union' is not defined

Expected behavior Builds without error

I looked into the codebase and looks like a simple import was missing: from typing import Union.

https://github.com/gitmylo/audio-webui/assets/15096514/afd4d79b-6f5f-48f7-9122-61e16d60e0ed

With this additional line, the server starts successfully. I can open new PR with this change, but it's strange that I'm the only one experiencing this kind of error.

[gitmylo]

That's odd, Union indeed does not have any issues when being used in my code without the import.

Maybe there's a difference between python 3.10.8 (mine) and 3.10.13 (yours) Regardless, I will add the import.
