fix: stop three loops that retry forever, and let budget dead letters recover

The event outcome worker re-requested PSTG and GROQ on every poll for as long as
the process lived, because a fetch failure only logged and continued while the
prediction stayed pending. Ten requests every five minutes, indefinitely. Per
ticker backoff now doubles to an hour, so a symbol with no market data costs one
request an hour instead of one a minute. It also translates dotted tickers the
same way the autonomy worker does, which is why that helper moved into the
shared price module rather than being copied.

The gdelt loop had no pause on its error path at all, so once the api started
refusing connections it spun through failures continuously, burning cpu and
filling the log with the same stack. It has been doing that for days. Backs off
to half an hour now and resets on success.

isTransientCoordinatorFailure matched 408, 429 and 5xx but not a budget 402/403,
so the 380 jobs that dead-lettered during the exhausted quota window could never
come back on their own, including 55 live events. Budget failures are transient
in a way an ordinary auth failure is not, and a wrong key still dies permanently
because it says invalid or unauthorized rather than naming credits.
