build: Auto-generate frontend API client

[MoritzWeber0]

Instead of maintaining our own frontend library, auto-generate a client with the OpenAPI Generator.

A new target make openapi was added. It can be used to auto-generate the new client according to the generated backend OpenAPI specification. To simplify the function names, the operation IDs are derived from the backend function names.

There are some issues with the generated code, e.g., anyOf relationships are not supported. However, we don't use them in many places and they can still be updated manually.

The main.js size has increased from 3.9MB to 4MB. This can be considered as irrelevant.

The /api/v1/projects/{project_slug}/models/{model_slug}/modelsources/git/validate/path route had to be moved to /api/v1/settings/modelsources/git/validate/path. Due to API generation issues, it accepts a JSON dictionary instead of a string. It didn't use the project_slug and model_slug and better fits to the general Git instances.

In addition, tests for the Git instance routes were added.

Thanks for looking into this and applying the initial changes. There are still a few services that make http calls that we should iteratively migrate to the generated ones so that we have no http calls left in our own services. I have ignored all the template and generated stuff in this PR due to the huge amount of changes and because I assume the generation works as expected.
There are only a few comments, mostly about some minor improvements that would be great to apply before we merge this PR.
