fix(restore): add pre-validation for truncated SQL dumps

- Validate SQL dump files BEFORE attempting restore
- Detect unterminated COPY blocks that cause 'syntax error' failures
- Cluster restore now pre-validates ALL dumps upfront (fail-fast)
- Saves hours of wasted restore time on corrupted backups

The truncated resydb.sql.gz was causing 49min restore attempts
that failed with 2.6M errors. Now fails immediately with clear
error message showing which table's COPY block was truncated.
