Subject: [PATCH] Fix store_accessor on MariaDB by declaring JSON attribute
 type

MariaDB represents JSON columns as LONGTEXT, which causes Rails to map
them to Type::Text instead of Type::Json. Since Type::Text lacks the
accessor method that store_accessor requires, this raises
ActiveRecord::ConfigurationError on MariaDB.

Adding explicit `attribute :column, :json` declarations ensures the
columns are typed as JSON regardless of what the database adapter
reports. On MySQL this is a no-op (already Type::Json); on MariaDB it
overrides Type::Text with Type::Json.

Fixes #2402
