Post TREX token deploy flow improvements

[dchernokur]

After deploying the new EIP-3643 token, the list of deployed tokens in "Admin" dropdown takes some time to show the newly deployed one, which leads to confusion "I've deployed the thing and I don't see it anywhere". We do have background refresh for the data, but it might be a bit slow, so we can improve the UX.

Suggestion:

• Check if we are invalidating the queries which fetch the tokens after deploy call
• Add "Refresh list" button which will reload the tokens upon click.
• Add "Close" button for the deploy token form, right now there is no proper way to navigate away from it.
• Add "Go to token" button to preselect just deployed token and open it as selected in the Admin area. Note that this might require reloading the list of deployed tokens first.

Considering we get list of deployed tokens from the events watcher, refreshing might not be that simple and we could be bound to the watcher timeout between poll calls 🤔 Let's figure out what can we do, maybe fake some loading spinner until new token pops in the list or something...
