Set contract auto-renewal

Sets whether the workspace's current contract term renews automatically or ends at term expiry. Choosing not to renew voids any unpaid renewal invoice; choosing to renew allows Brix to invoice the next term automatically. Returns 409 if the workspace has no fixed term, and 404 for white-label workspaces, where this setting does not apply.

Notes.

• Turning auto-renew off voids an unpaid renewal invoice.
