feat(tasks,server,web): bridge outbox events to the SSE bus (U3)

OutboxRelay gains a `mirror` option: listed types are claimed even without a
task route and, after the claim transaction commits, published in order to
the realtime bus (publish failures are logged, delivery state unaffected).
The worker mirrors feed.*, decision.*, download.*, organization.* and
subscription.* (feed.due excluded) with their business-id payloads, so the
home page, inbox, task stream and feed tables finally receive them. Feed
tables refresh on feed.fetched / feed.health_changed; the task stream also
listens to feed and decision events.
