feat(market): portfolio row-style redesign + per-wallet scope

Replace the drag/resize dashboard grid on the Market tab's portfolio with
three full-width row styles — compact (single-line), detailed (two-line),
and value-hero — cycled with Left/Right arrows like the Overview layouts.
Rows live in an internal scroll region bounded to the portfolio's height
budget, so the section stays put as groups are added.

- pfDrawRow renders each group in the selected style, reusing the icon /
  value / DRGX / 24h / sparkline pieces; per-entry field toggles honored.
- portfolio_style setting (0/1/2) persisted; arrow-key switcher + toast.
- Portfolio groups gain a per-wallet scope: new groups default to the
  active wallet's identity hash; legacy groups (empty scope) stay visible
  in every wallet. Scope filter drives both the height budget and the rows.
- Remove the now-dead grid machinery (mktDrawCard, pfComputeGridLayout,
  PfCell, PfGridDrag, MktCardCtx + MktCtx grid fields) — net code drop.
- Full UI sweep: seed demo portfolio groups + wavy price history and add
  market-rows-{compact,detailed,featured} surfaces so the styles are
  captured per skin (snapshot/restore the real portfolio + market data).
- i18n: portfolio_style_{label,compact,detailed,featured} + 8 langs; CJK
  subset rebuilt.
