feat(gui): tabs UI improvements (PR #2419)

* Adds "Reveal In Explorer" tab, to focus on on the current class's tree node

* Adds separators between tab categories, similar to how tabs look in VSCode/IntelliJ

* Rename from reveal_in_explorer to reveal_in_tree

* Minor fixes

* Handle mouse presses on tabs better

* use exist action name instead new one
