Make stream_settings optional in Inbound model

[F1bos]

Sometimes stream_settings can be an empty string, for example if inbound is socks proxy. Right now methods related to inbound will fail if it's socks inbound. This pull request fixes it.

Code to reproduce:

from py3xui import AsyncApi
import asyncio

async def main():
    api = AsyncApi.from_env()

    await api.login()

    inbounds = await api.inbound.get_list()
    print(inbounds)

asyncio.run(main())

Create a socks inbound and try running this code, it will fail with this exception:

pydantic_core._pydantic_core.ValidationError: 1 validation error for Inbound
streamSettings
  Input should be a valid dictionary or instance of StreamSettings [type=model_type, input_value='', input_type=str]
    For further information visit https://errors.pydantic.dev/2.9/v/model_type

@F1bos, hello!

Thank you for the PR!

Automatic checks are failing:

py3xui/inbound/inbound.py:106: error: Item "str" of "StreamSettings | str" has no attribute "model_dump_json"  [union-attr]

Please update the corresponding method, otherwise it will fail with AttributeError.

Sincerely

@F1bos, please fix the pylint errors:

py3xui/inbound/inbound.py:62:0: C0301: Line too long (114/100) (line-too-long)
py3xui/inbound/inbound.py:114:52: E1101: Instance of 'FieldInfo' has no 'model_dump_json' member (no-member)

And I'm merging it.

Thank you
