Native mods: a registered command run from a single player's owner console

The owner console (horizon-ctl command, the MCP command tool) ran every
line through the vanilla dispatcher, so a command a native mod registered
answered "Unknown or incomplete command". It now offers a registered name
to native_perform_command first, as the owner at level 4, the way the
owner's own chat does. The dedicated console was done in #5815.

Fixes #5682.
