Navigation menu refresh

We made some improvements to the navigation menu:

• We added icons to each menu item.
• The "Trading Partners" section has been renamed to "Partnerships".

• • The pages in the "Partnership" section are now ordered based on the onboarding steps you must complete: Trade Requests, Relationships, Scenario Testing.
• The "Setup" section has been renamed "Requirements".
  • The pages of the "Requirements" section are composed of your requirements (Communication Channels, Scenarios and Guidelines) and your consolidated partnership requirements (Integration Assistance).
• We added additional links to the Help section.

• The Visual Walkthroughs, previously available via the blue Orderful icon at the bottom right corner, were moved to the Help section under "Visual Walkthrough".
