Overview

Command: fill in environment on error logs captured before the column existed, using the rails_env recorded in environment_info at capture time.

Opt-in (rails_error_dashboard:backfill_environments). Live errors do not need it — FindOrIncrementError adopts a NULL row on its next occurrence — but history that never recurs would otherwise stay unbadged and unfilterable forever.

Runs in batches, one UPDATE per row: the value is inside a JSON text column, so it has to be parsed in Ruby and no portable single UPDATE can do it across PostgreSQL, MySQL and SQLite.
