Drop dead ProgramSummary.runner from dashboard types

The API's ProgramSummary no longer emits runner (a program has no launcher —
that lives on its deployment). Remove the stale UI type field and the
never-rendered Launcher row on the program detail page; a program's launcher
already shows on its deployment in the Deployments section.
