fix(integration-tests): update EventStreamService construction to 3-param ctor

WorkerLiveMxAccessSmokeTests built EventStreamService with the old
6-arg signature (mapper, dashboard broadcaster, logger) that predates
the SessionEventDistributor refactor; the current ctor takes only
(sessionManager, options, metrics). Pre-existing compile break on this
branch, unrelated to the doc sweep. NonWindows.slnx now builds clean.
