Pull Request Description

⚠️ This PR depends on #9896 and MUST NOT be merged before that one.

• Close Move to the Tab layout for Dashboard #9898
  • Move right menu to Drive View
    • Use new icon for toggling the menu
  • Move Search Bar into Drive View
    • both of these changes come with free simplifications to the code.
  • Refactor entire Top Bar to show pages as tabs

Important Notes

• Fonts containing slight variants have been added to make it match more closely with the Figma design. HOWEVER:
  • They have been added in app/gui2 instead of the Dashboard codebase, because that is where the existing Enso font is located.
    • While it's definitely possible to put them in the Dashboard codebase, I think it's preferable to avoid that, otherwise we will have two separate mechanisms for loading/packaging fonts.
  • However, this problem SHOULD go away if (if not when) the entrypoints for the desktop app (in app/gui2) and cloud.enso.org (in app/ide-desktop/lib/dashboard) are merged.
