Fixed focus issues with left side panel

- fixed issue where user had to tab twice to move focus to next category
- fixed issue where user had to press enter twice to select category.
- created custom surfaces to disable default focus/hover states by
  setting indication=null

Test: Manual, navigate through left side panel using tab and enter only,
ensure that you don't need to press tab twice or enter twice to navigate
or select category.
