Cancelling Client.list Creates Unrecoverable State for Client

## Environment

OS: Windows 10
Python Version: 3.13.7
aioftp Version: 0.26.2

## Problem

I think a problem in `list()` is it cannot handle cancellation and have the client recover properly because the buffers still contain data from the previous command. If we cancel in the middle of the `list()` call, `aioftp.errors.StatusCodeError` is raised when we try to run another command or call `quit()` in this case.

This can be reproduced with the following code:

```server.py
import asyncio
import aioftp
import pathlib

async def run_server():
root = pathlib.Path.home()
server = aioftp.Server(users=[aioftp.User("anonymous", "", base_path=root)])
await server.start("127.0.0.1", 2121)
print("FTP server running on 127.0.0.1:2121")
await asyncio.Event().wait()

asyncio.run(run_server())
```

if you uncomment `# clear_buffers()`, the `client.quit()` call is able to run successfully.

```client.py
import asyncio
import aioftp
import time
from contextlib import suppress

async def clear_buffers(client: aioftp.Client):
print("clearing buffers...")
while True:
await asyncio.sleep(0.250)
available = len(client.stream.reader._buffer)
if available == 0:
break
await client.stream.read(available)

async def work():
try:
client = aioftp.Client()
await client.connect("127.0.0.1", 2121)
await client.login(user="anonymous", password="")
lister = client.list("./", recursive=True, raw_command="MLSD")
print("Listing...")
results = await lister
finally:
print("DONE")
# await clear_buffers(client)
if client:
await client.quit()

async def main():
while True:
task = asyncio.create_task(work())
await asyncio.sleep(2)
task.cancel()
with suppress(asyncio.CancelledError):
await task

asyncio.run(main())
```

output without calling `clear_buffers()`...
