treewide: fix biome check errors

- Add radix parameter to Number.parseInt calls
- Ignore tailwind.css from biome (Tailwind directives not supported)
- Replace empty fragments with null
- Add biome-ignore comments for document.cookie and a11y
- Auto-fix: organize imports, remove unused variables, sort classes
