feat(ui): the deploy panel's run verbs carry the arm-driving bolt

The coaching work replaced the panel's Start/Stop pair with RunVerbs, whose
three verbs all start an inference session. Their `variant` is the
armed-state channel and their `title` carries the blocked reason, so they
cannot take RobotActionButton; the shared affordance rides on the icon
alone: the Play glyph inside each label becomes the bolt from
lib/robotActions.ts. Variants, title, aria-disabled and the ring are
untouched, and RunVerbs.test.tsx asserts nothing about the icon.
