[FEATURE REQUEST] Add Payment Pointer of sender when possible

[Tymmmy]

Describe the feature you would like to request

We would like to have the possibility of refund, or send back money available.
For now we can show the PP of the sender when they are sending from Interledger Wallet / Cards.
We should show in transaction details PP of sender not just name

Describe the solution you would like

Return from BE sender PP not just name
If available show in transaction details page sender PP
