Migrate Digital Passports to Supernet

• The previous transfer event will trigger the webhook that will call the migrateCertificateToSupernet.
• This builds the new digital passport history with the thread. The thread is into the digital passport content.
• The digital passport will be minted on the associated destinationNmp.
• The digital passport content will be updated on chain1 with the new thread.
• If the brand is not the owner, then the digital passport is airdropped to the previous owner.
