Problem: MarkdownPreview dispatched DOM CustomEvent via link.dispatchEvent()
which doesn't propagate through Svelte's event system. The on:verstak-link
handler on <MarkdownPreview> in NoteEditorPanel only catches Svelte dispatch()
events, not DOM CustomEvents from {@html} content.
Fix: Replaced DOM CustomEvent dispatch with Svelte createEventDispatcher.
Now handleClick() in MarkdownPreview calls dispatch('verstak-link', {...})
which properly propagates through NoteEditorPanel → App.svelte chain.
Also: removed unused importInternalLink import (was unused after
InternalLinkPicker replaced the manual modal).
