test(targets): pin the route over the folded glucose and heart-rate reads

The route test mocked Prisma and asserted a raw glucose findMany. The
glucose and resting-pulse inputs now come from their SQL readers, so the
test mocks those, feeds the pinned response through the in-memory fold,
and asserts that neither stream is read as rows.
