"""
KS2 attainment data re-importer.

Triggers a full re-import of the KS2 CSV data by calling the backend's
admin endpoint. The backend owns the migration logic and CSV column mappings;
this module is a thin trigger so the re-import can be orchestrated via Kestra
like all other data sources.

The CSV files must already be present in the data volume under
  /data/{year}/england_ks2final.csv
(populated at deploy time from the repo's data/ directory).
