Update the Wikitech documentation for Refine, including:
- A general review and refresh of existing content.
- Adding guidance on how to choose Spark job ingestion scale parameters, using Grafana topic size metrics as a reference point.
- how to deal with Refine errors
- updates to Ops week page on how to admin Refine on Airflow
- instructions on how to backfill refined event data (Example of 'hacky backfill')
This should help future maintainers tune resource usage more effectively based on real-time data.
