enhancement: 🎨 improve error message and request token flow on web UI

[iamnamananand996]

• Claiming testnet tokens from the official autonomysfaucet.xyz domain produces an error with the final [Request Token] action - 'There was an error in the request, try again' -> Does not indicate what the error is. Is this a manual or automated process?
• Requesting testnet tokens w/ verified Discord role is too long of a process
• Faucet claim process in Discord remains broken upon first try
• Network Settings on the autonomysfaucet.xyz/ is nice, but is there a way to one-click [Add Network] and it auto-populates the required field into your wallet solution? Currently using Metamask to test
