wendy+jacob+nick/eng 2908 users can manage approval requirements

[wendybujalski]

Users can now select a view on the diagram to see its approval requirements.
They can also select "Approval Requirements" from the menu on each view in the LeftPanelDrawer.
Users can add an approval requirement to a view and manage the users who are approvers on that requirement.
While the UI only allows creating one requirement per view for now, it can display multiple requirements if they exist.

Testing steps taken -

Testing with feature flag disabled

• Disable feature flag for fresh workspace
• Confirm that the flag is disabled by checking the Admin Dashboard
• Create a second view
• Add second view as component to first view
• Select the second view component - right rail should not change from NoSelectionDetails
• Open the LeftPanelDrawer and click on the DropdownMenu for a view - there should not be the option "Approval Requirements"

Testing with feature flag enabled

• Enable feature flag for fresh workspace, join the workspace with 2 separate users (incognito mode is helpful for this!)
• Confirm that the flag is enabled by checking the Admin Dashboard
• First user - Create a second and third view
• First user - Add second and third view as components to first view
• First user - Select the second view component, the right rail should display ViewDetailsPanel with "No Requirements For This View"
• Second user - also select the second view component in the same changeset, should see the same as first user
• First user - use the ViewDetailsPanel to add a requirement, the second user should see it appear as well
• Second user - add and remove users from the requirement, first user should see the changes in real time
• First user - swap between selected view components to make sure the info loads properly
• Finally, delete the requirement, both users should cleanly go back to the empty state for ViewDetailsPanel

Moving to drafts since we want to adjust the reactivity of the system with the flag on first.
