Decode a packed Predict order ID into (lower_tick, higher_tick, quantity),
with the quantity in USDC base units. For the order-flow companion's sell sizing
and remainder checks over order IDs Predict issued: it validates nothing. The
layout is Predict's frozen order-ID encoding: 30-bit ticks at bits 70 and 40,
and a 32-bit count of 10_000-unit lots at bit 100.
