TestFillPendingDetails_ReportsPhaseAwareProgressThroughActivitiesAndWorkoutsPhases
only ever called FillPendingDetails directly, never exercising
FullSync's own setProgress(PhaseDiscovering, ...) / deferred
setProgress(PhaseIdle, ...) wiring around backfillCore/
incrementalSyncCore -- what handleSyncRun actually runs in production
and what SyncModal's "Discovering activities..." spinner depends on.
Add a mock.Client.Delay field (slept, ctx-cancellable, at the start of
GetActivities) so a test can give the discovering phase real
wall-clock duration, then add
TestFullSync_ReportsPhaseTransitionsThroughDiscoveringToIdle, which
runs FullSync in a goroutine and polls Progress() to confirm it
observes PhaseDiscovering mid-flight and PhaseIdle after completion.
