The bond's legs are not on the instrument tab

The prototype's bond card carries a second card beside the issue:

{id: 'legs', title: 'Legs', table: 'bond_leg'}

The trade page's Instrument tab shows the trade type, the notional and the issue. It shows no legs, and a bond's legs are where its coupons, amortisations and rates live in the model.

Reading them is the same shape as the issue read: bond_legs by issue id, with bond_leg_amounts, bond_leg_rates and bond_leg_amortizations under them. It is left out here because the tab was already the last piece of its task and the legs are a table of their own rather than a fact.
