Implement Trello smart sorting by newest card activity

  - Update GetBoards SQL query with LEFT JOIN and GROUP BY
  - Sort by: 1) Has cards, 2) Newest card (MAX ID), 3) Board name
  - Update GetBoardsWithCards to match SQL sorting behavior
  - Leverage Trello ID chronological sortability (newer > older)
  - Active boards with recent activity appear first
  - All tests passing
