Fix textarea focus delay in Textarea.svelte

Modified the textarea component to import 'tick' from Svelte for future potential asynchronous operations, though not yet used in this snippet.
Increased the delay in the focus timeout from 0 to 100 milliseconds to ensure the textarea element is rendered before trying to focus it. This addresses issues with timing and focuses behavior in the UI component.
