Dashboard polish: banner brand, borderless forms, fix sidebar clipping

- Use intelidom_banner.svg as the sidebar brand instead of text
- Remove borders from admin cards, inputs, user rows, login inputs and
  ghost buttons (subtle fills / focus outlines instead)
- Fix sidebar clipping: height:100vh + padding overflowed the viewport;
  add box-sizing:border-box (+ overflow-y safety), drop divider borders
