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.

• openapi-python-client version [e.g. 0.19.1]

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).

使用提供的 OpenAPI 規格重現問題，然後檢查產生的 fast_api_client/api/default/client_client_get.py 中的匯入。產生的模型型別和用戶端型別不再衝突，且 ruff 在沒有 F811 錯誤的情況下通過時，修正就完成了。
