Kids' panel: definition icon on the open quest card only

The sealed card's tile goes back to the static star (the wax seal is
unchanged); only the open card resolves the definition's namespaced icon
(lucide/fa/emoji, legacy bare name as Lucide, star fallback). The
quest-log jsdom harness now reports each card's tile, and new panel
tests cover every icon kind, the fallback, and the sealed star. Bundle
rebuilt from this branch.
