- 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

Replace f-string interpolation with Databricks parameterized queries
using StatementParameterListItem in delete(), update(), and insert()
methods. Add column name validation in update() to reject invalid SQL
identifiers from payload keys. Embedding vectors remain inlined as
they are numeric arrays not supported by the parameterization API.
