Make gradient background fill entire content height

- Change from h-dvh to min-h-screen on main container
- Remove overflow-clip to allow content to expand
- Update inner containers to use min-h-screen for proper height
- Background gradient now extends with content rather than fixed to viewport
- Allows for scrolling when content exceeds viewport height
