- Persist built recipes to recipes table on /build so they get real DB IDs
and can be bookmarked via saved_recipes (FK was pointing at negative IDs)
- Populate missing_ingredients in build_from_selection() from role_overrides
vs pantry diff -- backend now owns shopping list computation
- Remove client-side cartItems tracking; shopping list derived from
builtRecipe.missing_ingredients instead
- Fix saved_recipes 422: mount saved_recipes router before recipes router in
routes.py so /recipes/saved isn't captured by /recipes/{recipe_id}
- Bump SaveRecipeModal z-index to 500 (above detail-overlay at 400)
- Replace "Add to pantry" primary action with "Grocery list" clipboard copy;
"Add to pantry" demoted to compact secondary button
- Default app landing changed from Pantry to Recipes tab
- Pre-fetch inventory on app mount so Find tab has data immediately
- Reorder recipe sub-tabs: Saved > Build Your Own > Community > Find > Browse
- Default active sub-tab changed to Saved
- Auto-redirect from Saved to Build Your Own when saved list is empty
- Add freeform custom ingredient input: typing a non-pantry item now shows
"Use X anyway" button so users aren't blocked on unknown ingredients
