ResolveFieldByName finds the single project field whose name matches name, case-insensitively. Matching is case-insensitive to mirror the Projects v2 platform API, which normalizes field names via a name_slug (name.downcase.gsub(" ","-")) and so guarantees field names are case-insensitively unique;
