Revise loans URL to not include user ID

Purpose: Revise loans URL not to include user ID, so that users can navigate to anonymized loan details without having user information.

1. Scenario: new loan URL without user ID
2. Scenario: reconsider popover display for loan details - what happens when user navigates to loan details
3. Scenario: what happens when user closes out of loan
4. Scenario: add link to borrower's name
5. Scenario: display of loan when anonymized
6. Scenario: new URL for open loans, closed loans that doesn't have user ID? likely the same unless it's behavior like requests (fetch all loans where user = X)
