Hey thank you for this just a small note on the SQL migration. Don't worry about the fmt ci failure it doesn't error for me locally and I don't see an issue if it keeps erroring ill investigate it.

Suggested change

mint_icon_url TEXT,

Since we want existing wallets to be able to upgrade to the new db scheme we don't want to change the init migration. Instead we need to create a new migration with the sqlx cli from within the wallet folder.

sqlx migrate add mint_icon_url

This will crate a new blank migration file where we can add the migration sql similar to the input_fee one.

ALTER TABLE mint ADD mint_icon_url TEXT;

We don't need to worry about migrating the redb database as its a new optional field it will simply be None. The migrations are a bit weird so let me know if you have any questions or would prefer me to push a commit for it.
