fix duplicate image IDs and migrate TitleImgParallax to Svelte 5 runes

Replace id="image" with class="image" in both Card and TitleImgParallax
components to prevent duplicate IDs when multiple instances appear on the
same page. Update TitleImgParallax to use Svelte 5 $props() and $state()
runes instead of legacy export let syntax, and modernize event handlers
to use onload/onclick attributes.
