Pretty straight forward. Left a couple comments.

The update portal authority ix looks good. Just to make sure I understand the changes required:

1. We need to update the portal_authority in the Earn program bc that allows us to unfreeze the M ATA that is owned by the new authority so that the portal has a "custody" token account to mint + transfer from. This PR solves that.
2. We also need to update the mint_authority on the M mint account from the current portal authority to the new one. I believe that requires the existing mint authority to sign the txn to do that. It seems like we either need to have an intermediate upgrade that has an ix that allows us to transfer this authority OR we need to add an instruction on the wormhole bridge adapter. I realized that the existing portal program has this functionality.

Correct. The portal authority also needs to be updated on Earn because its going to be signing the propagate index CPI
