feat(restaurant): orders list + settings

views/OrdersListPage.vue — grouped by day, source of truth is
STORAGE_SERVICE['restaurant.lastOrders.v1'] (newest first, cap
50). Each row deep-links to /orders/:id where the detail page
re-fetches the live order over REST so stale status never
displays here.

views/SettingsPage.vue — customer-side preferences persisted to
STORAGE_SERVICE['restaurant.settings.v1']:
  - currencyDisplay toggle ('sats' | 'msat'). Local display only,
    the extension is always msat-canonical.
  - relayOverride input (comma-separated). Reload required since
    RelayHub initializes once on boot.
  - 'Clear local data' destructive button — wipes cart, history,
    recent venues but does NOT refund/cancel placed orders.

Routes added: /orders, /settings.

Verified: vue-tsc -b clean against the whole webapp.
