fix(security): register EnsureSecurityOnboarded as persistent Livewire middleware

Re-applies the onboarding gate to /livewire/update component calls, not just the
initial page GET, so a component mounted while onboarded cannot run destructive
actions after the account is reverted to must_change_password mid-session.
Addresses the codebase-wide Codex finding flagged during the SSH-key-provision review.
