Wait for the boot as long as the boot takes

The specs added over this series each opened with an untimed check that the
canvas was there, which gives it Playwright's default five seconds. That is
the one wait in this suite that cannot be made faster: eight workers share a
software rasterizer, and what they are all waiting on is the same first paint.
Under a full parallel run five seconds is a coin toss, and it came up wrong on
the route-plotting spec.

Thirty, like every other wait in here that crosses a camera flight.
