Redesign recipe creation and edit view with Form-based layout and URL import

Replace the single "+" button with a 2-option menu (Create New Recipe / Import
from URL) across RecipeTabView, RecipeListView, and AllRecipesListView. Add
ImportURLSheet for server-side recipe import with loading and error states.

Completely redesign edit mode to use a native Form layout with inline editing
for all sections (metadata, duration, ingredients, instructions, tools,
nutrition) instead of the previous sheet-based EditableListView approach. Move
delete action from edit toolbar to view mode context menu. Add recipe image
display to the edit form.

Refactor RecipeListView and AllRecipesListView to use closure-based callbacks
instead of Binding<Bool> for the create/import actions. Add preloadedRecipeDetail
support to RecipeView.ViewModel for imported recipes.

Add DE/ES/FR translations for all new UI strings.
