New sidebar design with compact layout and improved navigation

New sidebar design We re-designed the sidebar to be more compact and scalable for upcoming features. It now shows more information and teams are sectioned better. Under each team, you can find their issues grouped into open and closed views. You'll also have the ability to see all issues in a list in addition to the existing board view. Together with the sidebar, we improved headers for better navigation and issue counts. We also added issue filters to all list views so it's easier to drill down issues based on different parameters. Copy issue ID and git branch name To make it faster to copy the issue ID or suggested git branch name, we added icons to the issue view sidebar for them. You'll still be able to get them through the action menu but this change should make copying easier for users who prefer to use a mouse.
