Thanks @AlexGherardelli for this!

My main concern is whether all these changes would be overwritten the moment we run an update of the autogenerated client?

Do we know if the open-api-generator has a template that uses uv?

[AlexGherardelli]

It looks like they do support uv: openapi-generators/openapi-python-client#1286.

Ok, great! I would then suggest to recreate the package automatically using this uv flag. It should create the all the files in this PR automatically. Any other custom changes would be overwritten anyways, so best to use the automatically generated content as much as possible, and limit custom changes to a minumum set of well-documented edits (like in point 4 here https://github.com/WFP-VAM/DataBridgesAPI/blob/main/generate/README.md)
