tiennm99 819d4a985e fix(stats): fan out per-key GetItem to avoid handler deadline timeout ...

Sequential List + N GetItem made /stats latency scale with the number
of tracked commands. On a cold Lambda container with ~25 commands the
cumulative DynamoDB round-trips can exceed the 10s webhook handler
deadline; the trailing chathelper.Reply -> b.SendMessage then fails on
a cancelled ctx and the dispatcher only logs the error, leaving the
user with no reply at all.

Fan the per-key GetJSONs out into goroutines joined by sync.WaitGroup.
Wall-clock latency collapses to ~1 round-trip while preserving the
per-key error isolation (a single GetJSON failure still drops only its
own row). Storage interface unchanged; no race regression vs. the prior
per-item write pattern.
