fix(dbus): pass isNewLaunch flag to fix LastLaunchedTime stats

sender() always returns nullptr when called across QObject
boundaries. handleUnitStarted on ApplicationService was using
sender() to determine launch tracking, causing
LastLaunchedTime/LaunchedTimes to never be updated. Use an
explicit bool parameter instead.

handleUnitStarted 在 ApplicationService 上通过 sender()
判断是否为新启动，但跨 QObject 调用时 sender() 始终为
nullptr，导致 LastLaunchedTime/LaunchedTimes 无法更新。
改为显式传递 bool 参数。

Log: 修复跨 QObject 调用时 sender() 失效导致启动统计不更新
Influence: 修复后 LastLaunchedTime 和 LaunchedTimes 能正确记录每次应用的启动时间与次数。
