test(harness): widen the deploy-seal timeout to match a real two-node deploy

Comparing full-suite runs on this branch against master in a clean worktree:
both fail 11 tests, 9 identical. Master's two extras are load-flaky unit tests
(AbCip Probe_loops, Galaxy EventPumpBoundedChannel); this branch's two extras
were both Host.IntegrationTests deploy-path tests — the area this change
re-times — so they are attributable here rather than to background flakiness.

Cause is margin, not correctness. These waits used to observe a coordinator
that sealed instantly on an empty expected-ack set; they now observe a real
ApplyAck round-trip from every configured node. 15s was enormous margin against
"instant" and thin against the real thing, so they failed only under full-suite
CPU contention.

Hoisted to TwoNodeClusterHarness.DeploySealTimeout (45s) so the reason is
recorded once rather than as four unexplained numbers.

DriverReconnectE2eTests is deliberately left alone: it seeds both ClusterNode
rows itself and unconditionally, so its expected-ack set is identical before and
after this change. Widening its timeout would be papering over a flake this
change did not cause.

Host.IntegrationTests 195/201; sole failure AbCip_Green_AgainstSim, verified
failing on master.
