test(dashboard): guard Stats wire object for KPI counts (SH-353)

The added service test asserts DashboardStatsDTO, which already carried
ScheduledTomorrow, PendingUplifts and AvetaPending, so it does not guard
the regression that was actually shipped: the DashboardController Stats
anonymous response dropping those keys and leaving the tiles empty.

Add DashboardControllerTests.GetStats_SerialisesKpiCountsOnWireObject,
which drives the controller and asserts the three keys are present on the
serialised wire object, so re-dropping any of them fails a test.

Also reword the pending-uplifts comment in DashboardServiceTests: the
Pending-only-vs-ChangesRequested exclusion is the behaviour the code
ships today, an open product call, not a settled review decision.
