🟢 - Ready for Review Flex schedule sub navigation to column on smaller screens

Reason for Change

As a user, when viewing the schedule page on a smaller screen, the schedule sub navigation shouldn't run off the screen.

Changes

Added a slightly smaller breakpoint, to the schedule CSS. Breakpoint adds a rule to display the Schedule Sub nav as a column on smaller screens.
