Amoy rehearsal: faucet points testers to the public Amoy faucet

anvil_setBalance doesn't exist on Amoy. The faucet now connects the wallet,
copies the address, and opens faucet.polygon.technology so testers fund their
own wallet with test POL (choose Polygon Amoy). Server endpoint returns the
faucet link + address instead of minting balance.
