AI routes had no consistent error handling — a provider failure (e.g.
OpenRouter returning a degraded-model error) crashed the route as an
uncaught 500 and, worse, still charged the user's monthly aiCall
quota for a request that never succeeded.
Adds withAiQuota()/aiErrorResponse() (lib/ai/ai-error.ts) and applies
them across all 12 AI generation routes: charges the quota, runs the
AI call, refunds the credit and returns a clean user-facing message
if it throws. Frontend needs no changes — existing dialogs already
toast whatever `error` string comes back.

Recipe cards, the recipe detail page, and meal planner still rendered raw
"{n} servings"/"{n}m cook"/"{n} srv" text and untranslated difficulty labels
outside the earlier i18n pass. Also wires the user's locale into AI features
that previously always answered in English regardless of app language:
recipe chat, ingredient substitution, recipe ideas, and generate-from-idea.
The recipe-language picker in the AI generate dialog now defaults to the
user's locale instead of always defaulting to English.
- Substitute finder never applied the user's BYOK/admin AI key (only fell
back to raw process.env), so it silently failed whenever the key was
stored via settings rather than a literal env var. Now resolves via
getDefaultProviderWithKey like every other AI route. Popover also
surfaces real error messages instead of swallowing failures.
- Ingredients with quantity 0 (salt, pepper, "to taste") rendered the
literal digit "0" in cooking mode, print view, public recipe page,
shopping lists, and serving scaler — several sites relied on generic
truthiness/filter(Boolean), which doesn't catch a stored "0" string.
Added a shared hasQuantity() helper and applied it everywhere quantity
is rendered, plus in the AI recipe-chat context sent to the model.
- Recipe chat panel rendered a duplicate close button on top of shadcn
Sheet's own built-in close X, producing a garbled overlapping glyph.
Removed the duplicate.
- Recipe chat assistant replies are markdown from the model but were
rendered as raw text; added react-markdown so formatting actually
renders.
