Which command automatically initiates a smart tunnel when a user logs in to the WebVPN portal page?

The 'auto-upgrade' feature governs automatic version upgrades of the AnyConnect or SVC client and is unrelated to initiating smart tunnel sessions at login.

There is no 'auto-connect' command in the ASA smart-tunnel configuration; this term does not appear in the webvpn smart-tunnel command set for automatic session initiation.

The 'auto-start' command, configured under the smart-tunnel group within the webvpn context, directs the ASA to immediately initiate the smart tunnel applet upon user login to the WebVPN portal page without requiring any manual user action.

There is no 'auto-run' command in the ASA smart-tunnel configuration; this term is not part of the valid ASA webvpn or smart-tunnel command syntax.
