fix: bound the market data fetch so the outcome worker cannot wedge

Live outcomes have been stuck at 4 while 35 matured live predictions sat
unscored, the oldest four days past its horizon. Running those three by hand
resolves them in 200-400ms each, so the data was there and the maths was fine.
The worker itself was wedged: up three days, last log 6 Sept, processing
nothing.

req.setTimeout only covers socket inactivity. A response that opens and then
stalls leaves the promise pending forever, and with it the entire loop, because
the fetch is awaited inline. There is now a hard bound around it.

This is the third time an unbounded await inside a long lived loop has silently
stopped a worker: the browser session in content, the content round itself, and
now market data. In every case the container stayed up, nothing threw, and
nothing was logged, which is the worst possible failure shape. So the worker also
announces what it is about to score, because an idle worker and a dead one
should not look identical from outside.
