Was only ever runnable once, buried inside base.sh's required-setup flow — no way to re-run just this step for a box that already went through base setup but needs another admin's key added later, or (the immediate case) a home box for services/vpn-data-mount.sh that only needs this one step. services/ssh-key-import.sh holds the real logic now (GitHub/Launchpad import via ssh-import-id, optional password-auth lockdown); base.sh's _base_setup_ssh chains into it the same way services/asterisk.sh chains into security-dashboard/pstn-trunk, with a degraded (no import, just ensures the SSH server itself is running) fallback for a pure standalone `sudo bash base.sh` run with no sibling files sourced. Independently runnable via `sudo ./setup.sh ssh-key-import` or `sudo bash services/ssh-key-import.sh`, and shows up in the whiptail menu under extras alongside ssh-config. Marked as never showing [installed] in is_installed()/install_count(), same as ssh-config — it's a repeatable management action, not a thing with an install state.
