Redesign orders/cart/search flows and fix RTL/auth edge cases in user-app

- Fix silent redirect-to-home for unauthenticated users on protected routes;
  now redirects to login with a return path
- Restyle OrderCard, SearchInput, Filters, DropDown, and product card image
  sizing/centering to match the app's LESS-token design language
- Fix ant-design Slider handle placement/drag under RTL and seed a valid
  default range so handles actually render
- Fix chip-row edge padding and top spacing across Orders/Cart/Search lists
- Add pull-to-refresh to the dashboard and fix its header/padding to match
  the fixed PageBar pattern
- Remove the floating WhatsApp button from index.html
