feat(theme-studio): realistic scenes for company, transient, and friends

Five daily-driver apps leave the generic face-name list: company (a completion popup with every row variant, inline ghost preview, tooltip search, and the echo frontend), company-box (the icons variant), transient (a magit-commit-style panel exercising every key class), magit-section (status-buffer headings with child counts and the highlighted section), and rainbow-delimiters (buffer-honest nesting depths 1-9 plus the cycle past 9 and both error faces). A new test gates realism: every face of each covered app must appear verbatim in its renderer, so a scene can't silently skip faces.
