fix(lint): resolve GCI import formatting and ModelConfig interface issues

- Fix GCI import formatting in modelpack package (remove extra blank lines, sort alphabetically)
- Update list.go to use ModelConfig getter methods instead of direct field access
- Fix list_test.go to use pointer receiver (&types.Config) to satisfy ModelConfig interface
