Description

Map each header individually to canonical fields (normalized comparison).

Tasks:

  • Create lib/mv/membership/import/header_mapper.ex
  • Implement normalize_header/1
  • Normalize mapping variants once and compare normalized strings
  • Build column_map (canonical field -> column index)
  • Early abort if required headers missing (email)
  • Ignore unknown columns (member fields only)
  • Separate custom field column detection (by name, with normalization)

Acceptance criteria

  • English/German headers map correctly
  • Missing required columns fails fast

External or internal Dependencies
