Display client names on calendar without using the filter#4815

You put back the way to display customer names but it is not by default. We always have to set the filter again and again.
The cookie for it is related to the session ! 😡
Please we should be able to decide our calendar view (for sur not monthly ! Who work on bookings with monthly view ? 😳)
with the customer names displayed by default. This is urgent as it is not UX at all.
