When the provider reports a lost connection,
we invalidate the doc query to refetch the document
data.
This ensures that if a user has lost is rights
to access a document, he will be redirected
to a 403 page without needing to refresh the page.
When users were reloading a 403 page, they were
redirected to the 404 page because of Nextjs
routing mechanism. This commit fixes this issue by
removing the 403 page from the pages directory
and creating a component that is used directly
in the layout when a 403 error is detected.
When we create a new user in the demo environment,
the email address will now follow the format
user.test@example.com instead of user@example.com.
"user" was only 4 characters long, it created failing
tests in the e2e suite.
