Owner opts in per-list via a new "Allow editing" toggle next to the
existing public-link switch. Anonymous writes are scoped to that one
list only — the link id is the sole credential, enforced in
getShoppingListAccess and the item routes (no session required there
now), with an IP rate limit on genuinely anonymous requests. Turning
off the public link also revokes editing.

Implements the six previously-unscoped feature ideas plus a mobile
layout fix reported via screenshot:
- Mobile: Recipes/Collections/Pantry/Meal Plan/Shopping Lists headers
now stack and wrap instead of clipping buttons on narrow viewports.
- Recipe diff/compare view: word/list diff against any past version,
next to Restore in version history.
- Shared meal plans & shopping lists: new shoppingListMembers/
mealPlanMembers tables (viewer/editor roles, mirrors
collectionMembers), share dialogs, membership-checked routes.
- PDF cookbook export: /print/collection/[id] renders a whole
collection with page breaks, using the existing print-CSS pattern
instead of adding a PDF rendering dependency.
- Grocery delivery handoff: shopping lists can copy-as-text (works
today) or send to Instacart once INSTACART_API_KEY is configured
(stub adapter — real API needs a partner agreement).
- Personalized "For You" feed tab: ranks public recipes by tag/
dietary overlap with the user's favorited/highly-rated history.
- PWA: added manifest.json + icons on top of the existing service
worker so the app is installable; cook-mode pages were already
cached for offline use.
