feat(frontend): add unified header and footer to public pages

Implemented consistent navigation across all public-facing pages with a
reusable layout system. Created PublicLayout component that wraps pages
with a header containing the logo and a footer with navigation links.

Changes:
- Created PublicHeader component with logo linking to homepage
- Created PublicFooter component with Product, Account, and Support sections
- Created PublicLayout wrapper component using flex layout
- Updated all public pages to use PublicLayout:
  - LoginPage, RegisterPage, ForgotPasswordPage, ResetPasswordPage
  - VerifyEmailPage, ContactPage, AboutUsPage, HowItWorksPage
  - NotFoundPage
- Fixed gradient background pages to use min-h-full for proper height
- Fixed content pages to avoid min-h-screen conflicts with flex-grow
- Updated About Us content

+To be fair, the original idea for this service was actually dropped on me by a friend who was tired of hunting for someone to film her dances – I just did what any backend developer / DevOps / Linux admin would do: said “okay, that shouldn’t be that hard… right?”, opened my editor, set up a few servers and scripts… and suddenly we had a new project on our hands 😅 I also had a not-so-secret teammate: AI. Without it, this would probably still be stuck in my “one day” folder for about a year 😄
