feat(channel-monitor): aggregate history to daily rollups + soft delete

明细只保留 1 天，超过 1 天聚合到新表 channel_monitor_daily_rollups（按 monitor_id/model/bucket_date 维度），聚合保留 30 天。两张表都用 SoftDeleteMixin 软删除（DELETE 自动改为 UPDATE deleted_at = NOW()）。聚合 + 清理任务由 OpsCleanupService 的 cron 统一调度，与运维监控的清理共享 schedule（默认 0 2 * * *）和 leader lock。ChannelMonitorRunner 的 cleanupLoop 被移除，只保留 dueCheckLoop。读取路径 ComputeAvailability* 改为 UNION 明细（今天 deleted_at IS NULL）+ 聚合（过去 windowDays 天 deleted_at IS NULL），SUM(ok)/SUM(total) 自然加权计算可用率，AVG latency 用 SUM(sum_latency_ms)/SUM(count_latency)。 watermark 表 channel_monitor_aggregation_watermark 单行（id=1），记录 last_aggregated_date，重启后从该日期 +1 继续聚合，首次为 nil 则从 today - 30d 开始回填，单次最多 35 天上限避免长事务。 raw SQL 的 ListLatestPerModel / ListLatestForMonitorIDs / ListRecentHistoryForMonitors 都补上 deleted_at IS NULL 过滤（SoftDeleteMixin interceptor 只对 ent query 生效）。 bump version to 0.1.114.28 GroupBadge 在 MonitorKeyPickerDialog 中复用平台主题色 + 倍率/专属倍率（顺手优化）。
