What does this MR do and why?

Fixes the following issues for Apollo boards:

• Sidebar should open when creating a new issue or epic
• Confidential, epic, health status and current iteration filters (currently failing due to missing filters transformation)
• Create new epic board
• When a board has a scope, a tooltip should display on the Edit board button
• Deselect active card on click
