Hero placeholder fieldname: vitec_hero_bgimage (content block prefix)

The vitec/herosection content block has prefixFields - the real column
and sys_file_reference fieldname is vitec_hero_bgimage; the JSON merely
strips the prefix. The first apply wrote the 20 references with the bare
name, so they existed but never rendered (no herosection anywhere had an
image, so there was no working example to catch it against).

- BuildProductOverviews: attach/backfill/skip-check now use
  vitec_hero_bgimage
- new migration fix_overview_hero_refs.php: renames the existing 20
  references in place (no re-attach) and sets the counter column
