feat: admin Ingredients CRUD UI; fix "page not found" after deleting shopping list/recipe/collection (v0.85.0)

Admin > Ingredients lets admins add/edit/delete canonical ingredients and their aliases (e.g. "sel"/"sel fin"/"table salt") without touching code — previously only settable by hand in packages/db/src/seed.ts. Deleting just unlinks referencing pantry items/recipe ingredients (onDelete: set null), nothing else changes.

Fixed: deleting a shopping list, recipe, or collection from its own detail page used router.push to navigate away, leaving the deleted resource's URL in browser history — one back-button press landed on a real "Page not found" screen. All three now use router.replace so the dead URL never sits in history.
