feat: manually create and edit batch-cook recipes

recipe-form.tsx previously had no batch-cook awareness at all — editing an
AI-generated batch-cook recipe and saving silently corrupted it (steps lost
their per-dish `appliesTo` tags, recipeBatchDishes rows went stale/orphaned,
since the create/update API schemas and edit-page query never touched them).

Adds a "batch-cook recipe" toggle to the form, an editable dish list (name,
description, fridge days, freezer-friendly/note, day-of instructions), and
per-step dish tagging (click a dish chip to mark which dish(es) that step
advances; empty = shared prep). Renaming a dish propagates to any step
still tagged with the old name instead of orphaning it. Wired through
Create/Update API schemas and the edit page's query/payload.

Verified locally: created a 2-dish batch recipe from scratch through the
real form, confirmed it renders identically to an AI-generated one (grouped
steps, dishes & storage cards), edited it, renamed a dish, reloaded, and
confirmed the step tag followed the rename rather than orphaning.
