improve receipt/details reports and implement number formatting

1) eager load reports for receipt/details
2) introduce number_format lookups to replace print_settings for number formatting
3) implement NumberFormattable concern, reference number_format lookups or print_settings if not exist, to get number format settings and number formatting
4) replace rails NumberHelper.number_with_precision with NumberFormattable.number_format hopefully to reduce overhead, formatting numbers for huge lists of data
