Delete Location (Hierarchical)

Purpose: To support deletion of locations. Looks like this is already partly done at the time of writing this (thanks, zburke!) but I need to get a story in with details and for tracking and testing.

User story:
As a user who has created a location record that is incorrect or a mistake
I want to be able to delete it

Scenarios:

1. Scenario
   • Given the Location edit form for a location that hasn't been assigned as a permanent or temporary location on any items or holdings
   • When displayed
   • Then a Delete button should display in upper right next to the Save and close button
2. Scenario
   • Given the Delete button
   • When clicked
   • Then a delete confirmation should appear reading:
     • Header: Delete location?
     • Body: <locationName> will be removed
     • Buttons: Cancel, Delete
3. Scenario
   • Given the delete button on the delete confirmation
   • When clicked
   • Then:
     • Location will be deleted
     • Location will no longer display in Settings > Organization > Locations
     • Location will no longer appear as an option when assigning a permanent or temporary location to an item or holding
     • Green toast confirmation will appear reading "<locationName> was successfully deleted."
4. Scenario
   • Given a location has been assigned as a permanent or temporary location on one or more item or holding
   • When it is displayed in edit mode
   • Then:
     • The Delete button should display per usual (UX for this will change in the future - UX-212 is tracking the design work for this)
     • Clicking delete should generate the delete confirmation per scenario 2
     • Upon confirming delete, another popup will display:
       • Header: Cannot delete Location
       • Body: This Location cannot be deleted, as it is in use by one or more records.
       • Button: Okay (button closes popup and delete has been prevented)
