Extract ingredient comments from food field, add import-to-both button

- Global post-processing in scrape() extracts trailing (comment) from
  ingredient food names into the extra/comment field. Works for all parsers.
- Added "Importálás mindkettőbe" button on single import page when both
  Mealie and Tandoor are configured.
