feat(ui): use recipes terminology in bulk delete confirmation for recipes page

The bulk delete confirmation modal always displayed "models" in its
text (title, message, countMessage) regardless of the current page
type. On the recipes page this is misleading since users are managing
recipes, not models.

- Add bulkDeleteRecipes i18n keys to all 10 locale files
- Update showBulkDeleteModal() to detect currentPageType and use
  recipes-specific wording when on the recipes page
