fix(jetbrains): use regular title weight in active lists

ActiveList titles were rendered bold for every row, which made Agent Manager, history, and settings lists read heavier than standard IDE lists and trees. Use the platform plain text style for the primary row title while keeping the explicit foreground so selected and deleting rows retain their color behavior.
