[android] Show "Opens / Closes X at Y" using formatter + add i18n strings

- Wire `PlacePageView.refreshOpenState()` to `OpenStateTextFormatter`.
- Keep <= 60 min branch with plurals (“Closes in %d minutes • at HH:mm”).
- Add day hint when next change is not today (“Opens Sat at 09:00”).
- Add localized strings with positional placeholders:
  - `opens_at` / `closes_at` (... `%s`).
  - `opens_day_at` / `closes_day_at` (`%1$s=%day`, `%2$s=%time`).
