Trusted Node Versioning Validation

[rodvar]

For androidNode we manage versioning directly using gradle because we have static control of it.

For the xClients, after the first release we will need some sort of versioning handshake to manage the app bisq required version (R) and the trusted node runing version (V):

• R <= V. -> proceed normally
• R > V -> Overlay error requesting the user to upgrade the trusted node, only option is to quit the client

From a UX perspective, I think the best is to present the user with the TrustedNode onboarding setup screen to give the option to connect to other trusted node, and also use the test button to verify it can connect and check if the trusted node upgraded its running version
