Update test expectations for DEFAULT NULL behavior
Fixed all test expectations to match MySQL's behavior where: - SHOW CREATE TABLE shows DEFAULT NULL for nullable columns - DESCRIBE/SHOW COLUMNS shows "NULL" string for default values - SHOW FULL COLUMNS shows nil for collation on numeric types Updated approximately 140+ test expectations across 16 test files to ensure compatibility with the new DDL behavior that adds explicit DEFAULT NULL to nullable columns. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
