feat: ask replace vs save-to-archive on regenerate recipe

When user clicks 'Generate another', show a choice:
- Replace (discard current, generate new) — former behavior
- Save to archive & generate new — saves current recipe first

All 5 languages (it/en/de/fr/es) with regen_choice_title,
regen_replace, regen_save_new keys.
