Fix step count mismatch when sequence packing is enabled (#5967)
* Fix step count mismatch when sequence packing is enabled

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Emit a single step-0 progress event and guard applyStatus totalSteps

Merge the two consecutive _update_progress calls before train() so the
step-0 gate in _on_progress fires once instead of twice, avoiding a
duplicate startup event and a null-metric step-0 row in training_metrics.

Apply the same positive-number guard to applyStatus that applyProgress
uses, so a stale or startup status poll can no longer overwrite the
packed step count with 0 or replace it with a stale total.

* Log debug message when train_dataset length is unavailable

The TypeError fallback for length-less datasets (e.g. streaming
IterableDataset) was silent, leaving no trace that the step estimate
came from the raw dataset rather than the packed one.
