feat: Add requests for supported entity types, version and localization

[kennymc-c]

I noticed that the Python UC API is missing the feature to send requests to the remote which is supported by the integrations api to e.g. check which entity types are supported. This is currently needed for select enttities that are not yet available for R2 users.
Disclaimer: This is just a quick ai supported draft and it seems to work for my use case but it has not yet been tested extensively. Please feel free to correct or note anything that might cause issues in other use cases.

Hi,

I have applied several modifications to make it work properly :

1. The websocket requests from integrations are handled correctly
2. I have added an extraction of the supported entity types in the startup of the driver (init function)
3. Each request for available entities will now filter the supported entity types

As I have done this on my repo, I have no idea how to update here or else I will make another PR ?

I could either close this PR for yours or you could commit to my fork and I will merge it so it will appear in this PR

Yes it is better to switch to the new PR as I am still doing some adaptations & improvements : this is not trivial where/when to put the extraction of supported entity types

All done and tested : #47

To test it and include it in the integrations :
python -m build on PR repository => this will generate an whl file in the dist folder
Just copy this whl in the source folder of the integration and edit requirements.txt with the right path like this :

ucapi
 file:./src/ucapi-0.5.4.dev3+geb80630e7.d20260201-py3-none-any.whl

This is what I have done for Kodi and it now works on Remote 2
