feat: add Reveal in Finder to editor header and tab context menus (#603) (#609)

Add a right-click context menu to the editor header file path button
with Copy Path, Copy Relative Path, and platform-aware Reveal in
Finder/File Explorer. Also add the same reveal action to the editor
tab context menu, and reorder tab close actions so Close All appears
above Close Tabs To The Right.
