- Add explicit type='TIMESTAMP' on StatementParameterListItem for
created_at/updated_at columns instead of relying on implicit
STRING->TIMESTAMP casting
- Fix pre-existing bug: update() used Python list repr [0.1, 0.2]
for embedding which is invalid Databricks SQL, now uses
_format_sql_value() to produce array(0.1, 0.2) syntax
