PostgreSQL error 0A000 (feature_not_supported) occurs when using
FOR UPDATE with aggregate functions like COUNT(*). Row-level locking
requires actual rows to lock.
Changes:
- Select id column instead of COUNT(*) aggregate
- Count rows in application using .length
- Maintains transaction isolation and race condition prevention

Backend: Enhanced matchField function with prefix and contains matching
so NHTSA values like "Sierra" match dropdown options like "Sierra 1500".
Matching hierarchy:
1. Exact match (case-insensitive) -> high confidence
2. Normalized match (remove special chars) -> medium confidence
3. Prefix match (option starts with value) -> medium confidence (NEW)
4. Contains match (option contains value) -> medium confidence (NEW)
Frontend: Fixed VIN decode form population by loading dropdown options
before setting form values, preventing cascade useEffects from clearing
decoded values.
