Incomplete models

[diacritics-owo]

Describe the bug

Some models are incomplete, leading to deserialization errors.

To Reproduce

There are likely more, but one example is Project. When requesting a project without versions, deserialization will fail, as client_side and server_side are "unknown", but the OpenAPI spec only defines "required", "optional", and "unsupported".

Expected behavior

The models should be complete, or at the very least default to some other value.
