Fix tootctl self-destruct not sending Delete activities for recently-suspended accounts (#16688)

* Do not block existing users' emails on self-destruct

That is wasteful and unintuitive

* Do not close registrations when running tootctl self-destruct with --dry-run

* Close registrations on self-destruct regardless of known remote accounts

* Fix tootctl self-destruct not sending Deletes for recently-suspended accounts

* Suspend local users even if no remote account is known

* Do not show scary confirmation text if ran with --dry-run
