Gracefully handle missing permissions / methods

[rolznz]

Currently we do not allow a user to create a wallet if it has missing permissions.

e.g. if list_transactions is not supported, only show an error on the transactions list that "List Transactions is not supported by your wallet.".
e.g. if pay_invoice is not supported, only fail when attempting to make a payment. This allows for receive-only wallets.

But what should be the hard requirements? get_balance and one of make_invoice / pay_invoice?

And what is better:

• Greying out the Send button (or)
• Showing error toast when trying to attempt a payment (Showing This app does not have the pay_invoice scope error)

And similarly hardcoding a "This wallet doesn't support listing transactions" over showing error

I personally feel showing less errors is better, but that would mean writing if/else code for these cases
