Changelog

[General] [Change] - redesigns business card for improved user experience

Test Plan

Look for bugs in the following:

• Ensure individual busyness card pages are no longer vertically scrollable and now comfortably fit 3 locations per page
• Ensure busyness pages split across multiple pages (e.g., Dining Halls (1/2) and Dining Halls (2/2)) appear and are next to each other regardless of reordering (e.g., if you see a page EXAMPLE (1/3), that card should be immediately followed by pages of the form EXAMPLE (2/3) and EXAMPLE (3/3)).
• Try enabling, disabling, and reorganizaing locations via the "manage locations" button
• Perform any misc testing with the busyness card you can think of (e.g., view busyness card when logged in or logged out, try reordering and hiding busyness card, etc.)
