Positions: "Open" button loads the position into the Strategy page

Each row has a new Open button that copies the order's legs (locked, since
they're real fills) into the StrategyStore basket for that symbol — wiping
only that symbol's basket (with a confirm if it already has legs) — and
navigates to strategy.html so you can analyze, roll or adjust the position.
