/**
 * Raises the per-field document ceiling from 10MB to 50MB.
 *
 * `max_size_mb` is what the portal enforces client-side (SmartFileInput blocks
 * the file and shows "File size exceeds the limit of NMB"), so the seeded 10
 * was the visible limit for every existing form even after the server-side caps
 * were lifted. The seeder only writes these rows on first insert, so deployed
 * environments keep their old value until this runs.
 *
 * Only rows still sitting at the old default are touched — a field an admin has
 * deliberately tuned to something else keeps that value.
