  Tests for displaying "required" badge in member overview.

  Tests cover:
  - "required" badge for required member fields (first_name, last_name, email)
  - "required" badge for required custom fields
  - No "required" badge for optional member fields
  - No "required" badge for optional custom fields
  - Badge is positioned in column header
