Show a "Paid" identifier in booking view of bookings paid successfully.

Instead of having to click into each booking to see the paid status, it would be helpful to have a column, colour or some type of identifier/icon of which bookings have been paid for in the bookings view. Perhaps adding another column in the list view, or having them highlighted in a colour when they are paid or unpaid. This would be helpful for the staff workflow of making sure appointments are paid for successfully.
