React to maintenance windows of Odysee servers

[kekkyojin]

The Issue

Steps to reproduce

1. Open the app when on the web account related features are unavailbe due to maintenance of servers

Expected behaviour

User should be told that some features are not available. Content should at least be listed

Actual behaviour

App gets stuck on splash screen. On Android 12+ it gets stuck on a blank UI.

System Configuration

• Android version: Any supported Android version

Anything Else

To avoid showing two different splash screens, on Android 12 and newer versions, UI is not updated until some information has been retrieved from Odysee servers. When those servers are down, this causes the blank screen to be stuck. That is not a bug, but the result of the app waiting for server's response or not reacting to request's timeout.

A fix to this bug must also take into consideration this fact.

Same PR may also update app's UI when device is offline
