Model named `Client` causes errors

Describe the bug
If a model of the Openapi App is called Client this name collides with the client.Client object in imports.

Additional context
The generator outputs:

Generating fast-api-client
Error(s) encountered while generating, client was not created

ruff failed

fast_api_client/api/default/client_client_get.py:8:30: F811 Redefinition of unused `Client` from line 7
Found 16 errors (15 fixed, 1 remaining).

In the relevant code there are two imports:

from ...client import AuthenticatedClient, Client
from ...models.client import Client

As hinted by ruff' error message there are two imports that load a Client object but they are loading different objects.
If you ty to use the generated code:

from fast_api_client import Client
from fast_api_client.api.default import client_client_get

with Client(base_url="http://localhost:8000") as client:
    data = client_client_get.sync(client=client)

print(data)

It will still work properly as the only Client type that is actually used at runtime is the one from models which is imported last (the Client from client is only used for type-hinting).

Tái hiện vấn đề bằng đặc tả OpenAPI được cung cấp, sau đó kiểm tra các import trong tệp được tạo fast_api_client/api/default/client_client_get.py. Bản sửa được hoàn tất khi các kiểu model và client được tạo không còn xung đột và ruff chạy qua mà không có lỗi F811.
