Gui taproot

If not too complicated i think it's worth hiding the network and Taproot selectors under a collapsible "Advanced settings" options at the bottom right before the buttons.

As @kloaec rightly points out 99% people want mainnet, not signet or regtest, and the 1% can use advanced settings. Same goes for Taproot for now.

Tried to put the pick_list behind an 'advanced settings' that would open a modal, but iced does not support the nesting of overlay iced-rs/iced#940
I am going back for the dropdown as suggested.

• Why are the advanced settings after the "Next" button?
• I get an error when signing with a simple "1 - 1" descriptor (signing using the primary key on the Ledger which is the internal Taproot key). Both for refresh and external payments.
• It seems change is not properly detected. Cf the screenshot.
  

My descriptor:

nit: i think the error message can just be "Taproot is not supported by this device". I think it would be clearer to a user.

I can't click on next anymore after removing the Bitbox from the path though.

When manually selecting coins, i can't click on "Next" when creating a spend.

I don't think the bug above is related to this PR. I also found #1024 which i don't think is related to this PR.

tACK b7f35c0 -- i've lightly tested this a couple times. It's good enough to get in and get tested along with the other changes.
