chore(spec): regenerate the os-regen artifacts on the merged tree

The os-regen driver kept the branch side of authorable-surface/ui.json and
the component reference page; regeneration restores main's
`ui/Action:outcomeMessages` beside this branch's record:line_items keys.

On a registered action, pairing this with a non-empty `params` is refused — that opens a second dialog for one decision; put the question on `description` instead. Correct on a param-LESS action, where the confirm is the only dialog there is. |

On a `type: 'api'` or `type: 'script'` action it may interpolate $`{result.*}` — the server response payload, the same scope `onSuccess.navigate` declares (e.g. $`{result.id}`). On a registered action that declares `outcomeMessages`, the entry named by the response's `outcome` is shown instead, and this message is the fallback. |
 | **errorMessage** | `string \| Record<string, string>` | optional | Error message to show when the action fails (overrides the raw error). |
 | **refreshAfter** | `boolean` | optional (default: `false`) | Refresh view after execution |
 | **opensInNewTab** | `boolean` | optional | Open the action result in a new tab. The renderer pre-opens the tab synchronously on click (popup-blocker-safe) and navigates it to the handler's redirectUrl. |
