Improve UX for descriptor registration

While testing the Jade implementation in Liana wallet i notice 2 important points:
In miniscript descriptors it's forbiden to reuse a key w/ the same multipath, so in liana we change the multipath for each occurence (<0;1>, <2;3>, <4;5>, etc...) when a key is used in several conditions. Multipaths are displayed in the descriptor template while registering a descriptor on jade, that is what i expected:


but multipath are also displayed while reviewing the keys:


- it is unnecessary and add a lot more in what the user need to verify, in the picture example, each key(total 4 keys) is use 3 time in the descriptor, so i have to verify 12 keys where in fact there is only 4!

- the jade never notify the user which key it owns, but it should!
