Calendar view filters partitioned Dags by partition_date, but the backfill path only set partition_key — so backfilled partitions were dropped from the calendar.

Why
The Calendar view filters historical runs of partitioned Dags by partition_date, but the partitioned-backfill code path only sets partition_key, leaving partition_date NULL. As a result, backfilled partition runs were silently excluded from the calendar. The scheduler already populates both fields when creating scheduled partition runs — this was an oversight on the backfill side.
What
partition_date=info.partition_datethroughcreate_dagrunincreate_backfill_dag_run_partitioned, mirroring what the scheduler already does.Was generative AI tooling used to co-author this PR?
