web/cobalt.css: optimised padding and safe area

- fixed top padding on iphones with dynamic island when installed as app
- unified padding with 2 variables
- smaller padding everywhere
- moved all safe area calls into standalone media query for mobile layout
- fixed dialog bottom padding
- minimised header and tab footprint in browser on mobile, allowing for more content on one screen
