Remove quote marks and styling from badge tagline

[marcoacierno]

What

Simplified the badge tagline rendering by removing the decorative quote marks (") that surrounded the tagline text. Also removed the associated .badge-tagline-quote CSS class and its font-weight styling that is no longer needed.

The tagline now displays as plain text without quotes, making the component cleaner and reducing unnecessary DOM elements.

ToDo

• Verify badge appearance in design/preview

Removes decorative quote marks from the badge tagline and the associated CSS class.

Check class removal: Before merging, confirm the deleted .badge-tagline-quote CSS class is not referenced in any print scripts, Puppeteer/Playwright configs, or PDF generation pipelines. Given the badge is used for physical printing, a grep across the full repo (including scripts/) would confirm it's safe to delete.

Unchecked TODO: The PR description has an unchecked item to verify badge appearance in design/preview. The badge layout is print-critical (physical conference badges), so this should be verified before merging.

Minor: tagline.substring(0, 250) will throw if tagline is explicitly passed as undefined from a call site (the default empty string only applies when the prop is omitted). Consider tagline?.substring(0, 250) ?? "" as a defensive fix.
