Ability to navigate to related Inventory Instance for POL

Purpose: To easily navigate between the POL and its related instance

As a staff person
I want to be able to click a button on a POL and go to its related Instance (if it has one)
So that I can easily navigate between the two records

Acceptance criteria

1. Scenario 1
   • Given the Purchase Order Line details view screen
   • When an instance record is linked to the POL
   • Then display Item details "Title" as a hotline to the inventory instance
   • AND when a user clicks on it
   • Then take the user to the Inventory app and the view of the related Instance

Notes

1. • • If they use the browser back button when on the instance, they should be able to navigate back to the POL details
     • If they are on the POL edit screen and there are unsaved changes, then display the unsaved changes modal before allowing them to navigate to the Instance

1. # Scenario 3
   • Ensure automated testing coverage for this new code is 80% plus and confirm with screenshot

NOTE May need a similar story and button to link to the Agreement when POLs can be associated with Agreements or Agreement lines
