feat: run startupservice in a new window from its error modal

When the startupservice fails, the modal is a dead end: the adapter returned
no log, so there is nothing to act on. The modal now offers a button that runs
the same service through the JES / STP web app in a new browser window, where
the SAS log is returned as the page body.

`_debug=131` is always added (the log is the point), and `_executionTasks` is
never included, so on Viya the run is not submitted as a Compute task and
cannot hit the execution-task timeout. The URL is built by `buildServiceUrl`,
which works for SAS 9, Viya and SASjs Server, and is the same shape the deploy
configurator already uses to open makedata.

The startup failure modals now carry the service name, which is what shows the
button: all three failure branches (malformed response, missing properties,
request rejected) pass `public/startupservice`.
