fix: customer form auth fields layout + sticky header opacity

- Auth fields: use grid-cols-2 with dir=ltr for proper username/password
  layout, better spacing and visual hierarchy with key icon
- Header: increase opacity to 0.95 with subtle shadow to prevent
  content showing through when scrolling
