Skip layoutId and use instant transitions on the card detail modal
when reduced motion is on. The shared layout animation kept the z-50
overlay in the DOM during its exit spring, blocking all card clicks
until it settled.

Replace 60/40 split layout with a 2x3 CSS grid where all sections
get equal weight. Cover color header, progress bar on checklist,
compact markdown editor, scroll containment on long lists.
Fixed React hooks rules violation where useState and useCallback were
called after a conditional return in BoardView. Removed unused
attachmentMode prop from AttachmentSection (can be re-added when file
dialog is wired up).
