Comment 7 for bug 1879983

Noting some enhancements that were pushed to the working branch:

- staff can now claim / unclaim responsibility for staging an appointment on the To Be Staged tab.
- The Staged and Ready, Patron is Outside, and Delivered Today tabs now include Items for Pickup / Items Checked Out columns. Those columns now also highlight holds whose shelf time falls _after_ the time that the appointment was staged.
- The last appointment slot for the day now falls _before_ the closing time, not on it.
- There is a new library setting, Disable patron modification of curbside appointments in public catalog, that prevents the ability of patrons to change appointments in the public catalog. This is meant to support workflows where the library wants to require that patrons call them to manage curbside appointments.
- The act of marking an appointment delivered can now trigger sending email receipts.
