ECTO PATCHES INSERT_ALL TYPE MISMATCH EDGE CASE

Ecto fixed a placeholder type validation bug in insert_all that was silently accepting malformed tuples.

The Ecto team shipped a fix [1] for issue #4742 that corrects tuple shape matching in the insert_all placeholder type mismatch check. The bug allowed certain type mismatches to slip through validation when the tuple structure didn't align with expected patterns. This is a surgical fix that tightens the validation logic without changing the public API. If you're using insert_all with dynamic placeholders, this prevents a class of subtle data corruption bugs that could have propagated to your database. The fix is already merged and ready for the next Ecto release.
