fix(recovery): No automatic reboot after rollback

- Directly invoke ConfirmRollback via QDBusInterface, bypassing
the proxy.
- Extend the timeout for the ConfirmRollback method call to 30
minutes.
- Prevent long-running rollbacks from failing due to the default
25-second DBus timeout.

fix(recovery): 回滚后没有自动重启

- 通过QDBusInterface直接调用ConfirmRollback，绕过代理
- 延长调用 ConfirmRollback 方法的超时，将超时设置为30分钟
- 避免默认25秒的DBus超时导致长时间回滚失败

Influence: 系统回滚
PMS: BUG-387145
