Brand glyphs in command overlay tab + history rows

Open tabs and History results in the command switcher now lead with the
brand glyph for their host (Notion, GitHub, Figma, Linear, etc.) instead
of a generic Globe / Undo2. The action rows still use IconName glyphs
because they map to internal navigation, not external sites.

Internal: split row rendering into render_row_inner so both the icon
and glyph variants share the same hover/click body.
