fix(playwright): enable shifts 3-5 via three save cycles

The assigned-site dialog gates the 4th checkbox on `data.thirdShiftActive`
and the 5th on `data.fourthShiftActive` — both bound to the dialog input
snapshot, not the live form control. So each flag only materialises after
a save + reopen. Loop three times: open dialog, tick the next checkbox,
save, close.
