Changes:
- ProductReviews.tsx: Use LEFT JOIN and fetch reviewer_name field
- ReviewModal.tsx: Store reviewer_name at submission time
- ProductDetail.tsx: Check is_approved=true in checkUserReview()
- Add migration for reviewer_name column and approval index
This fixes two issues:
1. Reviews now show real account names instead of "Anonymous"
2. Members no longer see "menunggu moderasi" after approval
