s.esmaeili f441ca8289 feat(user-apps): appearance settings (dark mode + reduced motion), product morph, filter sheet
Applies to both user-app and user-app-v2. Logic and structure are shared;
each app keeps its own look.

Appearance settings
- New "تنظیمات ظاهری" page (/settings/appearance), opened from the
  dashboard and available without login. It offers a light/dark/system
  theme and a "fast & light" motion switch.
- appearanceStore saves the choice to localStorage. A small inline boot
  script in index.html applies it before first paint so there is no
  white flash. The "system" option follows OS changes live.
- New ToggleSwitch component.

Dark mode
- Theme LESS tokens now compile to CSS custom properties. Light/dark
  values come from a generated virtual:palette.css (themeConfig/
  appearance.ts, with colors.json + new colors.dark.json).
- New LESS alpha() plugin replaces fade() on theme tokens.
- New semantic tokens: page, onInk, heroSurface, hairlineStrong,
  photoMat, photoStage.
- The dark palette is layered (page < card < panel < border) so
  surfaces separate without shadows.
- Hard-coded colors were replaced by tokens according to their role.
- antd inputs/text get dark overrides; vant uses its own
  .van-theme-dark.
- Light mode looks the same as before.

Reduced motion
- With html.motion-reduced, transitions are capped at 120ms, keyframe
  loops stop, and backdrop blurs and permanent will-change are dropped.
- Spinners and the toast progress bar (which closes the toast) are
  exempt via .keep-motion.
- Carousel autoplay, the v1 Lottie and the product morph honor the
  setting.

Product detail
- Opening a product is now a container-transform morph from the tapped
  card (ProductMorph). It replaces the bottom Drawer and uses composited
  transform/opacity only.
- The detail view is seeded with the card's data, so it no longer
  opens blank and jumps.

Filters and sheets
- Filters are now a full-width bottom sheet. Selections stay a draft
  until applied, so the result list no longer re-renders while
  dragging the slider.
- DropDown collapse animates grid-template-rows instead of a capped
  max-height.
- v2 IslandSheet is restyled to the v2 design language (API unchanged).

Fixes
- filtersStore.reset() shallow-copied shared arrays, so clearing the
  filters never cleared the selected brands.

// Adapted from legacy singleProduct.vue's own fetch (GET /product/:id).
// The new API has no single-product-detail endpoint (only GET
// /catalog/products, the flat list) — apps/api is out of scope for this port,
// so this fetches the full list and finds the matching product client-side.
// Wasteful for a large catalog, but honest: no fabricated endpoint, no silent
// behavior change.
//
// `initial` seeds the page with the ProductSummary the tapped card already
// holds — the same shape, from the same endpoint — so the detail view renders
// complete on its first frame instead of mounting blank and jumping when the
// fetch lands. The fetch still runs, silently, and only replaces the product
// if the server's copy actually differs (stock moved since the list loaded).
//
// The silent refresh waits until the opening morph (ProductMorph.vue, ≤420ms)
// is over: the response is the whole catalogue, and parsing it — or swapping
// the product and re-rendering — mid-animation drops frames.
