Add a prompt when interacting with an identity server without terms

Browse source 
This adds a prompt whenever we are about to perform some action on a default identity
server (from homeserver .well-known or Riot app config) without terms. This
allows the user to abort or trust the server (storing it in account data).

Fixes https://github.com/vector-im/riot-web/issues/10557
