Redirect to login page when session ends

[chippison]

Description

UX-305
We no longer want to show multiple error messages on screen when the session ends either with the user just leaving the computer for a long time or the session cookie was deleted. We want to redirect the user to login page when this happens

Please include a description of this change and which issue it fixes. If no issue exists yet please include context and what problem it solves.

Is there a way how to test this in a UI test? We can load a dashboard, log the user out or delete their session cookie or similar, and reload the UI with the expectation of them landing on the log in page.

I've did some further local testing on this one. While it works nicely when switching between menu entries it now fails with a generic error if you e.g. click on the refresh icon in a dashboard widget.

As everything should use the AjaxLoader to load content it should work for all cases when moving the 401 check here:

matomo/plugins/CoreHome/vue/src/AjaxHelper/AjaxHelper.ts

Lines 535 to 540 in b26fa85

	}).fail((xhr: jqXHR) => {
	if (xhr.status === 429) {
	console.log(`Warning: the '${$.param(this.getParams)}' request was rate limited!`);
	reject(xhr);
	return;
	}

I've added the change here instead of in WidgetLoader

Thanks @sgiehl
