fix: resolve practice by question set id; set Response flags on question-sets by-owner

- GetSubModulePracticeByID matches sub_module_practices.id or question_set_id
- Prefer primary id when both could match (ORDER BY + LIMIT 1)
- Set Success/StatusCode on practice GET/detail and GetQuestionSetsByOwner
