Display transaction fees in normal mode

[murisi]

Describe your changes

Updated the test vector generator to require the hardware wallet to display wrapper transaction fees in normal mode. See attached the test vectors (which show what the hardware wallet will be required to display) resulting from this change: testvecs.json . This PR should not be merged before hardware wallet normal mode fee display support is implemented because that would cause the hardware wallet CI tests in this Namada repository to fail.
