Subject: [PATCH] perf(providers): optimize gateway error rate query to avoid
 unnecessary view joins

The query was using microdollar_usage_view which joins 13+ tables via LEFT JOINs,
but only needs columns from microdollar_usage and microdollar_usage_metadata.
Query now directly joins only these two tables.
