feat: add opts to requireUserSession for error message and status code customization

[dethdkn]

Hello, This PR introduces the ability to customize the status code and error message in the requireUserSession method. This feature is particularly useful for applications that are not in English.

I use the returned error message on my apps, and I wish I could translate the Unauthorized message to my language

Thank you for the PR @dethdkn

Don't you want to translate on the application side instead of the API @dethdkn ?

[dethdkn]

Hey @Atinux I translate both 😅, Most of my $fetch are like this

const res = await $fetch('/do-something', { method: 'post', body: body.data })
    .catch((err) => { toast.add({ title: err.data.message, icon: 'i-heroicons-exclamation-triangle', color: 'red' }) })

I get the returned api message and show it as a toast I'm not sure if it's the best way to work with $fetch catch, but, it has been working here since my api have multiple throws.

Also sorry for the inconsistent spacing on the opts type, I thought eslint would fix that

Happy to fix the conflicts with the new eslint rules? see #79
