fix: correct DB column names in tournaments/shop/achievements APIs

- tournaments: use created_at instead of non-existent start_time
- tournaments frontend: use started_at/completed_at columns
- shop: guard against non-array response when table missing
- achievements: use correct table names and column ordering
