What github issue is this PR for, if any?

Resolves #1734

What changed, and why?

Court mandates now have an "implementation status" field. Only admins and supervisors can add or edit this field from a given court mandate, but volunteers can still see this field.

Acceptance criteria:

• Only supervisors can edit implementation status.
• Implementation status should display as a dropdown menu, with the following items in it:
  • not implemented
  • partially implemented
  • implemented
• When nothing is selected in the dropdown menu, the default (first item) should be: set implementation status
• On desktop web, implementation status should appear to the right of each court mandate.
• On mobile web, implementation status should appear underneath each court mandate.

How will this affect user permissions?

• Volunteer permissions: Can now see (but not add/edit) case mandates implementation status.
• Supervisor permissions: Can now add and edit implementation status of case mandates
• Admin permissions: Can now add and edit implementation status of case mandates

How is this tested? (please write tests!) 💖💪

Automated specs:

I basically expanded on the specs I've created in #1802.
I tested whether or not admins, supervisors and volunteers could see, add, or edit the implementation status of court mandates.

Manual testing

Admin/Supervisor:

1. Login as admin/supervisor
2. Go to the cases page, choose a case and click Edit
3. Click "Add a court mandate"
   • Check if the text area and select box show up
   • Check if the select area has the correct fields
   • Check if the select area is displayed beside the text area in desktop
   • Check if it is displayed below the text area in mobile, with enough space between the court mandates to avoid confusion
   • Add more court mandates to check the same conditions but with other court mandates
4. Click "Update CASA Case"
   • Check if the saved court mandate fields show up with the same info as before
   • Check if it looks the same as before, but now with a delete button alongside the fields

Volunteer:

1. Login as volunteer
2. Go to the cases page, choose a case that has court mandates and click Edit
   • Check if the disabled text area shows up
   • Check if a text with "Status: [status name]" shows up for each court mandate
   • Check if the implementation status text displays correctly in both desktop and mobile
