Pull Request Overview

This pull request implements functionality to automatically open FAQ accordion items when the URL contains a hash fragment, addressing issue #142. The change replaces the previous onMount approach with a reactive Svelte pattern using the $page store.

• Replaced onMount lifecycle hook with reactive statement using $page.url.hash
• Added checked prop to Accordion component to control initial open state
• Simplified hash handling by removing direct DOM manipulation
