Murisi/compress hw displays rebased

[murisi]

Describe your changes

This PR was obtained by rebasing #4436 on main (ff17969). An attempt to reduce the amount of screens clicked through on the hardware wallet for shielded/unshielding transactions. This is done by displaying the payment address of a note as the sender (similar to what the Zcash Ledger app does) instead of the extended full viewing key that owns it. This reduces the number of screens required to display a sender from 8 to 3. I.e. there's now 5 less screens to click though, which reduces the amount of time required to sign a shielded transaction once the display lag is considered. Alternative options were considered like displaying just a full viewing key or an incoming viewing key instead of the extended full viewing key, but these do not already have bech32 encodings in Namada nor can they be used in any of the existing interfaces. See attached what the new test vectors would look like: testvecs-fmted.json.gz and testdbgs.txt.gz.
