fix(showcase): responsive card, full localization, in-game stat icons and clean PNG export

Layout: card now fills its container (3/2/1 columns) with no horizontal scrollbar.

i18n: every modal/showcase/console string follows the selected language, named fallbacks for th/en plus English fallback for other locales, localized character names and light-cone passive text.

Showcase stats use the official in-game property icons (same set as the overview tab) instead of emoji, including the element DMG icon.

Export: fixed 1200px clone with poster metrics, cover-cropped splash art (html2canvas ignores object-fit), transparent background so the rounded corners have no dark wedges, and a two-pass measurement inside the capture iframe so the PNG is never cropped.
