fix(lint): add nolint comments for gosec G201/G104 in dolt storage

The SQL formatting warnings (G201) are safe because:
- Placeholders only contain "?" markers for parameterized queries
- WHERE/SET clauses use validated column names with ? placeholders
- Refs are validated by validateRef() before use in AS OF queries
- LIMIT values are safe integers from filter.Limit
