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).

提供された OpenAPI 仕様で問題を再現し、その後、生成された fast_api_client/api/default/client_client_get.py の import を調査します。生成されたモデル型とクライアント型が衝突しなくなり、ruff が F811 エラーなしで通過すれば修正は完了です。
