- Add retry/backoff (429 + 5xx, Retry-After aware) to the OFF adapter so
transient API errors no longer abort a run.
- Clamp bounded text fields (serving_size, net_content_unit,
country_of_origin) to their column widths in transform; long OFF values
previously raised StringDataRightTruncation and rolled back the batch.
- Load each record inside a savepoint (load_record_safe) so one malformed
source record is skipped instead of aborting the whole import; jobs now
report an errored count.
- Tests for retry behaviour, serving_size clamping, and per-record isolation.
