Subject: [PATCH] Add a shared helper for lookup field case normalization

Nine trigger scripts across the compliance and SSU modules had each copied this loop verbatim. The LookupValidationHelper is passed in rather than created internally so callers keep it at script scope, where its cache of allowable values is read once per batch instead of once per row.
