fix(ui): finish HiDPI pass — cosmetic ×dpiScale, narrow-width reflow, recent-list reserves

The tail of the DPI/font-scale/responsiveness audit — ~26 remaining findings.

Container / recent-list (Theme-1 leftovers):
- Send: drop NoScrollbar|NoScrollWithMouse on ##SendFormScroll so Recent Sends is
  reachable at font_scale 1.5 (parity with receive).
- Receive: cap the QR/form card via std::min(mainCardTargetH, availH - recentReserve)
  so RECENT RECEIVED stays on-screen (identity at 1.0x).
- Wallets dialog: size the capped-mode list to whole rows so it no longer clips a
  partial row / crowds "Create a new wallet".

Narrow-width (1024px) reflow:
- Console toolbar reserves space for ALL trailing controls (both icon toggles + zoom
  buttons) so the +/- zoom no longer runs off-window.
- History sort combo sized to its measured widest localized label ("Newest first").
- Settings Theme/Layout/Language row: scale the wide→stacked breakpoint by dpiScale so
  it drops to full-width stacked combos at 1.5x (Consolidated Card no longer clips).
- Recent-tx type label: derive the address column X from the measured label width so it
  can't collide at narrow widths.
- Mining Recent Pool Payouts: floor the panel height to fit the empty-state caption.

Cosmetic ×dpiScale() on absolute geometry (no-ops at 1.0x): mining SOLO|POOL toggle &
idle combos, market pair-chips, password/PIN strength bars, receive/send currency
toggles, explorer search bar/rows/rounding, About-card logo, chat empty-state wrap,
recent-list address/time offsets, address-toolbar & two-row action buttons, console
line-gap/status-dot/pane rounding.

Verified at font_scale 1.5 and at 1024px across full-node + Lite + Windows (ctest
green) and an adversarial diff review (one over-reserve regression fixed).
