Manufacturer authenticity verification

Add a Manufacturer Authenticity workflow where owners of high-value or vintage instruments (e.g. a Fender Stratocaster) can submit an authenticity review request directly to the manufacturer, including instrument details and photos, and receive a digital Certificate of Authenticity linked to that specific instrument in Sonority. The approved instrument can display a visual verification badge (similar to a social media “blue tick”), with manufacturers receiving most of the verification fee as an incentive to participate.
