The tests probe a free port (bind 0, release) and start the SDK server later; under a
highly parallel run another test can take the port in between and the SDK fails with
'Failed to establish tcp listener sockets for Ipv4 and IPv6.'. OpcUaHostStart.StartAsync
builds a fresh host + server on a fresh port per attempt (up to 5) when the failure is a
bind failure; all 45 start sites in OpcUaServer.Tests, OpcUaServer.IntegrationTests and
Runtime.Tests use it. Per-attempt GUID ApplicationUris are hoisted out of the host factory
because a changed URI against a reused PKI store fails with 'Cannot access private key'.

Native conditions support AddComment / commented Acknowledge, so the comment (and its
ClientUserId) is condition state the rebuild dropped. And the deferred restore report
re-stamped Time with the carried instant even when a client method call had reported a
newer event in the restore->complete window; it now reports at the node's current Time.

A full RebuildAddressSpace recreated every native Part 9 condition inactive +
acknowledged, and when the alarm-tag set was unchanged (e.g. one
UnsTagReference added to an alarm-bearing raw tag) nothing re-told the new node
its state: the host does not re-subscribe for an unchanged set, and Galaxy /
OpcUaClient have no snapshot to replay anyway. Active alarms read normal until
their next device transition.
OtOpcUaNodeManager now captures each NATIVE condition's live state (from the
node, so a client-applied ack is kept) before the rebuild clears, restores it
when the same id is re-materialised native in the same apply, and reports ONE
condition event per restored off-normal condition at the new
IOpcUaAddressSpaceSink.CompleteAddressSpaceApply (after notifier wiring).
Unclaimed captures are discarded there, so a later re-add is fresh. Quality is
carried silently for normal conditions too (it is only re-annotated on a
connectivity edge). Scripted conditions are untouched (#487 re-asserts them).
OpcUaPublishActor calls CompleteAddressSpaceApply at the end of every apply.
