Fix issues from CodeClimate

[simenandre]

We currently have 31 issues on Codeclimate. I think we should fix them, but after Project Barebone is done, of course.

Most of these issues are duplication (22); typical example:

Similar blocks of code found in 2 locations. Consider refactoring.

<Box sx={{ mb: 5 }}>
	<Flex sx={{ width: '100%', justifyContent: 'center' }}>
		<Heading as="h3" sx={{ flexGrow: 1 }}>
			Ordrestatus
		</Heading>
	...

The rest (9) are in complexity; typical example:

Function Orders has 55 lines of code (exceeds 25 allowed). Consider refactoring.

const Orders: React.FC = () => {
  const navigate = useNavigate();
  const data = Array(10).fill({
    orderNumber: '00001',
    orderDate: '26.05.2020',
	...
