Drain Faucet feedback and UX

[da-kami]

It would be great to get (immediate) feedback from Drain Faucet in the form of a transaction id so the user know if it worked or not. Our faucet does return a txid if it works, but the user does not see any feedback until the wallet picks it up which can be up to a minute time.

Without feedback the user might actually trigger Fund me repeatedly until the wallet / tx history is updated. The user can trigger it again as long as the wallet has a balance of 0 on record.

I propose to add feedback before we navigate back to the Dashboard:

1. Don't jump to Dashboard but wait for the response of calling the maker's faucet and provide some information to the user.
   1. If there was an error returned display the error; the user can then try again
   2. If success was returned:
      1. display the transaction ID (to be returned in the response) and change the Fund me button into a Close button to navigate back to the Dashboard.
      2. Lock the Fund Me button after we received a success response (not just on the balance)
