chore: Limit the number of CTAs on the Primary Card (#34)

Displays a dynamic list of primary course buttons, managing up to
four views: Due, Future, Upgrade, and Resume. Views are shown in
priority order: Due, Future, Upgrade, and Resume.

If all four views are available, the Future view is removed to ensure
a maximum of three buttons are displayed. Any unavailable views are
omitted from the list, maintaining the defined priority.

Fixes: LEARNER-10139
