What

https://github.com/stellar/hubble/issues/407

Repartition tables to use closed_at at the daily grain

Why

Remove dependency and weirdness with partitioning on batch_run_date. closed_at is a much more standard and relevant column

Known limitations

• Update downstream dependencies (query filters on batch_run_date, dbt models, etc...)
