fix: correct openapi.ts schemas against actual route code (v0.27.1)

Audited every documented request/response schema against the real
Zod validators and NextResponse.json shapes across all route
families, then fixed drift: missing batch-cook/tags/photos fields on
recipes, wrong comment/rating shapes, meal-plan entry shape (day vs
dayOfWeek, nullable recipeId), shopping-list/pantry response fields,
a phantom GET /webhooks/{id} with no backing route, and numerous
missing 400/401/429 response codes.

Also fixes a real bug found during the audit: the webhook-redelivery
route returned {error: object} instead of the app-wide {error:
string} convention on validation failure.

+### Fixed
+- API Reference (`/docs`) schemas corrected against the actual code across the whole API — recipes (batch-cook fields, tags, photos were undocumented), comments, ratings, meal plans, shopping lists, pantry, feed, and several missing error responses. A webhook-redelivery route also returned a malformed error body — now matches the rest of the API's `{ error: string }` convention.
