Fast add settings: Default suppress from discovery value

Purpose: Some institutions will want their fast add records to be suppressed from discovery by default while others will not. The purpose of this story is to allow institutions to set their preferred default at a tenant level.

User story statement(s):

As a member of the circ staff
I want my fast add records to be automatically set with the correct value for "suppressed from discover"
so I don't make mistakes and set it incorrectly

Options:

1. Settings page - This is the ideal option but will require backend work. Mockup: https://drive.google.com/file/d/1K0qpuznqQkckxtNmzWcCorTY-8s6Hsh0/view?usp=sharing
2. Tenant config - Team says this could also be done in tenant config, which would not require backend work

Scenarios (assuming option 1 is selected):

1. Scenario:
   • Given Inventory settings
   • When displayed
   • Then the Instance, Holdings and Items section should display a "Fast add" option
2. Scenario:
   • Given Settings > Inventory > Fast add
   • When displayed
   • Then:
     • Page header: Fast add
     • Controls:
       • Cancel - Close without saving
       • Save & close
       • X - Same as cancel
       • Save and Cancel only become active when form is "dirty" (has unsaved changes)
3. Scenario:
   • Given Settings > Inventory > Fast add
   • When displayed
   • Then "Default suppress from discovery" should display:
     • Dropdown menu
     • Values = Yes, No
     • Default = Yes
     • Note (and this is out-of-scope for this issue), the default here will impact the "Suppress from discovery" value in the Instance record
4. Scenario:
   • Given Settings > Inventory > Fast add form is dirty
   • When I try to navigate away before saving changes
   • Then the standard unsaved changes popup should display
