Add Borrower Name and Patron Group to Loan Details Header

Purpose: To add this element for usability and consistency with other pages.

*User story: *
As a user who has accessed loan details from outside of the Users app (e.g. from check out, check in, requests etc)
I want to see the Borrower's name very prominently displayed on the page
So I have important context for what I am looking at

Scenarios:

1. Scenario
   • Given the Loan details page
   • When displayed
   • Then the Borrower name and patron group should display in the page header like it does on Loans (see attached screenshot)
