chore: handle min max values in lnurl withdraw

Description

Fixes #159 although it needs some review of the design. This might be also problematic in small screens.

Here's the design:

• Send to LN address
• Withdraw

Some notes:

• Just redding the amount + always displaying the range and redding it too will be sufficient I think
• I think we don't need any confirmation with all details when paying to LN address, most wallets don't do it and it's and additional step
• I'd appreciate any progress to matching the design in this 2 flows (I need to revise other flows a bit), but that can be seperate issue

Send to LN
