I haven't systematically been through but I think there a few places like this where you shouldn't need to declare the types so you can just get rid of them
| return ( | ||
| <Button | ||
| className={`bg-foundation text-white rounded-full ${className || ''}`} | ||
| <Link |

Buttons like Message Seller only work if you click on the button text at the moment! I thought there was something wrong with their click handlers/links but then I realised the issue is only the text was being turned into a link
(I might not have got the class/css stuff right here)

maybe this isn't the right thing to return, I was being lazy
I think it should be impossible for a logged out user to reach this component so this could actually be a legit time to use userID! on line 13!

this here is some pure typescript magic called a 'type predicate'. the item is Item bit means 'what I'm going to return from this little fn is of type Item', and this does away with the annoying (Item | undefined)[] situation you were in before. Just using the filter without this type predicate magic annoyingly doesn't convince Typescript that you've got rid of the undefineds (even though you have)

With the changes here and in fetchItemDetails I think a bug should be fixed where at the moment if you try to view your favourite items but you don't have any, the whole page crashes
