* fix(v-navigation-drawer): update drawer states reactivity with permanent

fixes #2493

* Create failing test cases

* simplfied logic, fixed tests, added one

* remove overlay when being resized from mobile to desktop and active

* run tryOverlay when temporary toggles

* test: use expect().toBeTruthy()

* Remove booting from drawer

 - Prevents the initial animation on non-ssr pages
 - Uses a ref hack to set the correct styles on content elements - see
