[Attendance] Fix formatting of last name

[aaron_bahmer]

Problem statement:

When looking at student names in Attendance, their last name appears formatted as bold. We have individuals whose last name consists of two words. When their name appears in Attendance, only the last of those two words is bolded. Since formatting doesn't display, I will use * to surrounded *boldface* text. For instance: Consider William Sitting Bull, whose Canvas "sortable name" appears as Sitting Bull, William William's name appears as William Sitting *Bull* when it should appear as William *Sitting Bull*

Proposed solution:

Change the coding for the Attendance pages such that the entire last_name string is formatted in boldface. Please make this change in respect to those families who have multiple-word surnames.
