Move the live NET readout from the panel center onto the tab sub-bar

The pending trade's credit delta now sits at the right end of the
Buy/Sell + Buyback sub-bar, past a hairline divider — tabs AND the
credit math on one console, one glance apart (entry state dims it to
0 cr). The center column keeps Confirm/Clear (re-centered); the
buyback panel's Confirm moves up to sit just below its rows.

Knobs: data/shopui.json → preview (bar sizing, zeroColor, divider).
Docs: docs/ECONOMY.md §12 mockups + bullets follow the new layout.
Tests: dev/shop-ui.test.mjs asserts the bar's NET readout mirrors the
pending trade (+N cr while picking, 0 cr after Confirm).
