60 s labelled a slow-but-clean large rebuild degraded. The deadline moves to a
shared Commons DeployTimings constant that ConfigPublishCoordinator reads, and
the node's timeout is deadline - 15 s margin, so the held ack still lands in
time. A timed-out ack's reason now says the outcome was not reported in time,
distinct from a real sink failure.

The apply writes the node's row Applied/null before the address-space outcome
is known; central adds the reason only when it ACCEPTS the ack, so a discarded
(stale/timed-out) ack left a fused node's row reading clean. The prefix moves
to ApplyAck.DegradedReasonPrefix so both writers spell the row identically.

DriverHostActor no longer acks Applied the moment the revision advances. It
asks OpcUaPublishActor for the outcome (RebuildAddressSpace.ReportOutcome) and
acks Applied+Degraded(reason) when the apply was degraded; a missing outcome
times out (60 s, inside the coordinator's 2 min deadline) to a degraded ack,
never a clean one. Re-dispatching a revision whose apply was degraded or is
still unconfirmed re-applies instead of taking the clean idempotent
short-circuit - that re-apply is also what repairs the degraded nodes.
Tests with a bare publish probe use a clean-outcome auto-pilot probe.
