refactor(db): use version string as primary key for ConfigVersion

-transition `of_config_versions` primary key from `id` to `version` string.
-add database migration files `202606270001_make_version_primary_key.sql` for PostgreSQL and SQLite.
-introduce AfterFind/AfterCreate GORM hooks to preserve JSON backward compatibility.
-refactor API controllers, logics, and front-end typescript definitions to receive `string` parameter.
