Brave (and maybe other browseres) refuse to set the 'User-Agent' header
in XMLHTTPRequests, and are vocal about this in the debug log. Since the
OpenAPI code generator always outputs a custom 'User-Agent' header, I've
added some JS code to strip that off when constructing an API client.
Remove a whole lot of `console.log()` calls. They were useful during
development, but not really suitable for production environments. Because
they also include (potentially large) objects, they can even slow down
the webapp itself.
The code to fetch the task log tail is moved from `JobsView.vue` to
`TaskLog.vue`, as that knows exactly when it's shown & hidden.
The subscriptions to the task log updates will have to be managed in the
same way; that's for another commit.
