Refactor - Static nav links through page meta config

Created by: deepakduggirala

Instead of importing nav store and using nav.setNavItems, static nav breadcrumbs can be set through route meta data.

<route lang="yaml">
meta:
  title: Users
  requiresRoles: ["operator", "admin"]
  nav: [{label: "Users"}]
</route>

router.beforeEach((to) => {
  if (to?.meta?.nav) {
    nav.setNavItems(to.meta.nav);
  } else {
    nav.resetNavItems();
  }
});

router.beforeEach needs to registered in main.js to be able to run when directly loading the specific url
