How can I move (or create another) publish button?

Dig in Core

All admin UI pages use a core function for a reason:

submit_button( $text = NULL, $type="primary", $name="submit", $wrap = true, $other_attributes = NULL );

There’s also get_submit_button() in case you want to return instead of print the button.
