fix(queue): draw the scrim only where it can be tapped

Below 600px `.panel-content` is `width: 100%`, so the scrim sat
entirely underneath an opaque panel -- measured at 424x439, host,
panel and scrim all 424x318. It dimmed nothing and dismissed nothing
there while wearing `cursor: pointer`, so #24's tap-outside-to-close
did not exist on the device it was drawn for.

Of the issue's two directions this takes the second. A gutter is the
drawer pattern and buys the affordance by taking width off a
full-screen surface on a 424px viewport; #55 already made the queue a
*screen* at that width, whose ways out are back and a 44px close
button. So there is no scrim there rather than an unreachable one.

Existence is `matchMedia` rather than `display: none`, on `job-band`'s
rule: a hidden scrim is still an element carrying the handler. The
600-899 band, where the panel is a 320px column of a wider content
area and the scrim has real uncovered pixels, is untouched.

The e2e half asserts *absence* at 424x439 rather than clicking,
because a phone-width case that clicks the scrim's centre hits the
panel and passes on the broken build -- which the issue anticipates.

Closes #171
