Controls in this task

New appointment for a caller opens admin-new-appointment.html; Open opens the one sample detail screen (the mockup does not pick the state from the row).
View, confirm, reschedule and cancel are on the detail screen, with the words “This texts the customer.”
The filters and search are drawn, not working.

?

? Whether the search here duplicates Customers (name, phone, plate). Drawn so staff can find an appointment without leaving the list; the client may want one search.
? Calendar by month only (drawn); a week or day view waits on how many appointments a day has. Waits on the client.
? The daily capacity count in the calendar is per day, not per service or window. Waits on capacity (open question).
? Paging for a long list: not drawn, the list scrolls.
