Service API: Use { data, error } Format, No try/catch

• When calling a service API (e.g. from @/services/...), the service returns { data, error }.
• Do not use try/catch. Await the call, then check if (error).
• If error: show Error toast (showErrorToast(error)), reset any relevant state, set loading false, and return.
• Otherwise use data and set loading false.

// ❌ Avoid: try/catch around service call
try {
  const res = await getPhysicalProductPrices({ ... });
  setPrices(res?.data ?? null);
} catch (err) {
  showErrorToast(getAxiosErrorMsg(err));
} finally {
  setLoading(false);
}

// ✅ Prefer: destructure { data, error }, check error, no try/catch
setLoading(true);

const { data, error } = await getPhysicalProductPrices({
  physicalProductId: productId,
  selectedItems
});

if (error) {
  showErrorToast(error);
  setPrices(null);
  setLoading(false);
  return;
}

setPrices(data ?? null);
setLoading(false);
