fix(auto-dim): dim org-superstar's heading stars and list bullets

Bullets were the last thing left lit in an unfocused org window. org-superstar puts its own face ahead of the org face beneath, so a heading star renders as (org-superstar-header-bullet org-level-1) and outranks the org-level-1 we already dim.

Three of its four faces flat-dim. The fourth, org-superstar-leading, takes the -hide face instead: its foreground is the background colour, which is exactly what keeps hidden leading stars invisible. Flat-dimming it would reveal stars I chose to hide. A test says so, so nobody completes the set later.

That closes the dimming work. The parenthesised text from the first report turned out to be org-code and org-verbatim, already covered.
