- Rename Vue plugin export to GnexusUiVue while keeping VMKUiVue alias;
  add tryUseRouter, tryUseRoute, isRouteActive composables.

  main/module/exports to gnexus-ui-kit aliases.

- Update modal/drawer/toast demos to exercise the browser JS API.
- Update functional tests for dynamic modal/drawer creation.
