Proposed Changes

• Minor fix to Sidebar height after updating the Button.
• Decreased layout's padding on smaller screens.
• Added responsiveness to LeftArrow
  • Moved component to SubBoards, as it can receive a isLast prop to render or not a vertical bar.
  • Replaced the line_long icon with a div, as it can be responsive in height.
  • Added a div that acts as a vertical bar that connects to the next card.
• Refactored SubBoards logic to use filter instead of conditional rendering.
• Refactored CountCards HTML so it doesn't separate the numbers from the label.
• Refactored CenterMainBoard to use Button instead of a div to collapse the sub-boards.
• Refactored CardBody and CardEnd to support wrapping.

Note: I noticed that this PR became bigger than I expected, so I can split this in 2 if needed.
