Fuzebox navigation redesign

We have made updates to the sidebar, header, and breadcrumb elements of Fuzebox. The new elements incorporate previously missing functionalities, enhance navigation, and present a sleeker appearance that is compatible with desktop, tablet, and mobile devices. This update also provides improved support for users who have access to multiple Merchants. By utilizing the new Customer menu located in the top left corner, you can now search and filter all screens based on a specific merchant.
