This PR fixes a few UI issues with the sidebar
1. `z-index` issues with sidebar dropdowns
2. Move the event listener to the root of the dropdown container, it
allows more consistent behaviour of the trigger, earlier the click on
the trigger when the dropdown was open would cause the container to
re-render
3. Use `perserve-open` for the status switcher menu item in the profile
menu.
4. Use `sessionStorage` instead of `localStorage` to preserve sidebar
dropdown info. When opening the dashboard without directly going to a
specific route, any previous known item would get expanded even if it's
link was not active, this caused issues across tabs too, this fixes it.
5. Use `snakeCaseKeys` instead of `decamelize` we had two packages doing
the same thing
6. Update `vueuse` the new version is vue3 only
