i18n: translate meal/drink pairing, nutrition, comments, DMs, people search, URL import

Full sweep of hardcoded English strings across:
- Meal pairing and drink pairing dialogs (titles, descriptions, role/
  type labels, regenerate/generate buttons, progress labels) — also
  fixed drink type labels that had French text hardcoded regardless
  of locale ("Sans alcool"/"Chaud").
- Nutrition panel — had no useTranslations at all.
- Comments: header, empty/loading state, post/reply/cancel/delete
  buttons, relative timestamps (just now/Xm ago/Xh ago/Xd ago), and
  comment-reactions' toasts + aria-labels.
- Rating stars toasts.
- Direct messages: thread, conversation list, message button, both
  /messages pages.
- People search page and component.
- URL import dialog (title, description, buttons, toasts).
