When a floor is fully booked the blue/gray available/booked highlights do not load at all. This gives users the impression that the highlight has failed to load and there is an application error.

I see that as of v2023.02 a message has been added indicating there are 0 rooms available. This is an improvement but it could be more clear.

For a floor that is 100% booked for the selected date/time:
- Display the highlights showing all rooms gray - this will also allow admins to review bookings for fully-booked floors at a glance.
- Make the message more prominent, for example a popup stating "no reservations available for your selected time frame."
