chore: Migrate github.com/jinzhu/gorm to gorm.io/gorm

[eternal-flame-AD]

Closes #862 .

I removed the manual column fixup: The default column type is already bloba and longblob (I tested on the docker container for MariaDB and postgres).

I also dropped a test that is basically if the database returns error then the function has to return an error, feels a little mechanical coverage driven test not really useful.

Code looks good. I'll try to test this with all supported databases on sunday, or next week.

I checked the unique index now generates correctly on postgres. Thanks for the catch. The primary key one doesn't look super actionable right now, the current behavior looks fine to me (migrate the foreign key to a supertype but keep primary key as is on an existing DB)

[jmattheis]

postgres and sqlite looks good, but mysql/mariadb has some problems.
