TV build setup

[mykhailodanilenko]

🚀 Description

In this PR the tvOS and Android TV builds are added to the pipeline and the application is adjusted to running on TV. Also, the documents are updated to reflect the necessary steps to buid and edit the TV versions of the app. In https://github.com/mykhailodanilenko/web-client/actions/runs/11729401208 you can see the resulting artifacts, I tested them on all platforms and can confirm the apps are able to build and run. Next step in TV development will be to adjust the app to TV remote navigation.
