chore(backend,nextjs): Introduce treatPendingAsSignedOut option to server-side utilities and control components

[LauraBeatris]

Description

Allow passing treatPendingAsSignedOut to auth, getAuth, and server-side control components.

If session status is pending:

// Returns signed out object by default
const { userId } = auth()

// Treats as signed-in
const { userId } = auth({ treatPendingAsSignedOut: false })
