feat(lifelog): 统一「设置」tab — 集中所有可调参数

新增第 6 个 tab「设置」(SettingsScreen.kt)，把散落各处的配置收进一页： - 纪要：会话间隔 / 自动跑周期(改完即重排 WorkManager) / 会话最短语音 / 后端模型(2B/4B/Hermes) - 声纹：聚类阈值(0.45–0.65) - 本地模型端点：baseUrl / 2B / 4B model 名(ChatConfig) - 录音/电池：白名单状态 + 申请配套把写死的参数改成可配： - SummaryWorker：KEY_PERIOD_MIN / KEY_MIN_SPEECH_SEC，min-speech 从 prefs 读 - SummaryScheduler：周期从 prefs 读(默认 15，硬下限 15) - SpeakerClusterer：thresholdFromPrefs()，RecorderService 的 live 聚类器 + SpeakersTab 的 reclusterAll 都用 prefs 阈值 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
