Suggest optimal amount to successfully complete a full Cash out

[deerwhisper2310]

Is your feature request related to a problem? Please describe.
When I try to cash out from a mint (let's say i want to withdraw to my LN address in my nostr profile) and I want to move ALL of my full balance (top right corner), I get told the balance is too low. I have to do the math and try again to get the exact number that will allow me to complete the withdrawal after accounting for fees.

Describe the solution you'd like
Perhaps after hitting 'Estimate fee', if the total including fee is > the available balance, Enuts automatically calculates the difference (prompting the user to hit a button that inputs the new amount and tries the payment again). This would create a much better withdrawal UX as I wouldn't have to do the math myself (less frustration and faster tx).
