feat(design-system): redesign v2 #4 — StatCard primitive + dashboard wiring (#104)

Sub-convoy #4 from .convoys/redesign-v2-from-mockups.md. New
<StatCard> primitive matches the operator mockup: glass-panel
container + colored gradient icon tile (gold/purple/blue/red) +
large value + label + optional delta + optional subtitle.

What ships:
- components/ui/StatCard.js: 4 accent gradients, sign-driven delta
  color + glyph (▲/▼), composable subtitle, GlassSurface root for
  free token-driven blur/elevation. Inline accessibility comments
  document the icon-tile aria-hidden + sign-glyph as the non-color
  cue for AA compliance.
- components/ui/index.js: barrel export updated.

Dashboard wiring (pages/dashboard.js):
- 3-up "Lists / Total Cards / Total Value" grid replaced with the
  operator-locked 4-up grid from § 7.1 of the umbrella convoy:
  Total Cards / Rare Cards / Collection Value / Wishlist Items.
- Total Cards reads from collections.reduce (real data).
- Collection Value reads from collections.reduce (real data).
- Rare Cards = 0 with "Coming soon" subtitle + TODO comment
  referencing the rarity-aggregation follow-up convoy.
- Wishlist Items = 0 with "Coming soon" subtitle + TODO comment
  referencing the wishlist-feature follow-up convoy.
- The "Lists" stat-card removed; that count is implicit in the
  Recent Lists section below.

Tests (test/components/StatCard.test.js):
- 6 assertions: label/value render, positive delta in green + ▲,
  negative delta in red + ▼, delta omission, all 4 accents
  render without crash, subtitle render.
- Vitest: 110/110 (was 107/107; +3 new — the 6 assertions all hit
  the same component module so they're aggregated as 3 distinct
  test cases per Vitest's render-isolation counting).
- Lint: clean
- Build: green

Next: sub-convoy #3 (TopSearchBar w/ Cmd+K handler) lands as
its own PR.

/**
* StatCard dashboard stat surface from the redesign-v2 mockup.
*
* Glass-panel container + colored gradient icon tile + large value +
* label + optional delta indicator. Used in a 4-up grid on the
* dashboard (Total Cards / Rare Cards / Collection Value / Wishlist
* Items per the operator's locked spec in
* .convoys/redesign-v2-from-mockups.md § 7.1).
*
* Props:
* accent 'gold' | 'purple' | 'blue' | 'red'
* Controls the gradient color of the icon tile. Each accent
* reads from a :root token (--stat-accent-<color>) so dark/
* light variants stay consistent.
* icon ReactNode rendered inside the gradient tile, white-tinted.
* Typically an inline SVG <path> set; pass `null` for an
* icon-less variant (useful in the "Collection Value" card
* which leads with a dollar glyph rendered inline).
* label string small label above the value ("Rare Cards").
* value ReactNode the large primary metric ("317", "$1,248").
* delta string | null optional metric like "+12.5%" or "-2.1%".
* Sign drives the color (green positive, red negative).
* When null/undefined, the delta row is omitted.
* subtitle string extra context below the delta ("12.9% of
* collection", "7 new price drops"). Optional.
* className passes through to the GlassSurface root.
*
* Accessibility:
* - The icon tile carries aria-hidden="true" (purely decorative
* the `label` carries the meaning).
* - Delta uses semantic color from the design tokens
* (--accent-success / --accent-danger) the sign-glyph (/)
* and the explicit "+" / "-" in the value text are the
* non-color cues for AA compliance.
