feat(lifelog): 定时不录（quiet hours）— 设定时段自动暂停采集、到点恢复

- QuietHours：可配时段（跨午夜支持，如 23:00→07:00），存 lifelog_prefs - RecorderService 重构为 reconcile()：采集 = 非手动暂停且非静音时段；每 30s 调和，到点自动停/起。手动暂停彻底释放 wakelock；静音时段保留 wakelock 供定时器到点恢复。统一了手动暂停/恢复与定时不录两条路径（capturing 单一真相 + statusText 去重通知）。 - RecorderState 加 isQuiet；首页状态显示「🌙 静音时段（自动）」、秒表冻结 - 设置页「录音/电池」段加定时不录开关 + 起止时刻（整点）；30s 内生效，无需重启服务真机验证：窗口外正常录音（reconcile→录音中，回归通过）；窗口内自动转「静音时段」停采集、秒表冻结；关窗口后恢复。测试用窗口与服务状态已还原。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
