Resolved a critical parsing error in leads_view_lead.svelte due to incorrect Svelte class directive syntax.
Addressed multiple svelte/no-at-html-tags linting errors across the following files to mitigate potential XSS vulnerabilities and improve code safety:
- src/routes/events_leads/exhibit/[slug]/leads_add_scan.svelte
- src/routes/events_leads/exhibit/[slug]/leads_manage.svelte
- src/routes/events_leads/exhibit/[slug]/leads_view_lead.svelte
Replaced {@html} blocks with safer Svelte conditional rendering ({#if}) and direct interpolation ({value}) for static and dynamic content where appropriate. Removed commented-out {@html} tags that were still triggering linting errors.
