feat: shopping list rename/delete, item reorder+categories+search, ingredient-quantity parsing fix

- Fixed a real i18n bug: the checked-count line called the wrong
  translation namespace and rendered the literal key on screen
- Shopping lists can now be renamed and deleted from both the list index
  and detail pages (API already supported delete; rename was net new)
- Root-caused "long list UI is off": meal-plan-generated lists never set
  an aisle, so every item fell into one undifferentiated "Other" bucket
  despite the grouping UI existing. Added a keyword-based aisle guesser
  wired into list generation (fallback only, never overrides an explicit
  aisle) plus a one-click "auto-categorize" for existing lists
- Items can now be reordered by drag-and-drop within a category (dnd-kit),
  recategorized via a dropdown, deleted, searched, and sorted (category /
  alphabetical / unchecked-first); searching flattens the grouped view
- Fixed a separate bug: AI-generated ingredients sometimes embedded the
  quantity/unit in the name itself (e.g. "2 cups flour" as one string).
  Added extractIngredientQuantity() as a Zod transform at both recipe
  create/update routes (the choke point every creation path funnels
  through) to split it back out, plus schema descriptions on the AI
  ingredient schemas as a prevention layer

New migration 0028 (shopping_list_items.sort_order), left unapplied like
the others. Verified with typecheck, lint, and a clean --no-cache docker
build.
