fix(channel-monitor): drop soft delete, refactor feature flag to declarative form

### 后端修复：日志表不该用软删除 channel_monitor_histories / channel_monitor_daily_rollups 都是日志/聚合表，没有恢复需求。110 里加的 SoftDeleteMixin 会让 DELETE 自动变成 UPDATE deleted_at，导致行和索引只增不减，徒增磁盘占用和查询成本。改回分批物理删（参考 OpsCleanupService.deleteOldRowsByID 模板）： - ent schema 移除 SoftDeleteMixin，重新 go generate - repo 新增 deleteChannelMonitorBatched 辅助 + 两条 prune SQL 常量（WITH batch AS SELECT id LIMIT 5000 → DELETE IN batch） - DeleteHistoryBefore / DeleteRollupsBefore 改调分批 raw SQL - 移除 ComputeAvailability / ComputeAvailabilityForMonitors / UpsertDailyRollupsFor / ListLatestPerModel / ListLatestForMonitorIDs / ListRecentHistoryForMonitors 等 raw SQL 中的 deleted_at IS NULL 过滤 - UpsertDailyRollupsFor 的 ON CONFLICT 去掉 deleted_at = NULL 重置 - migration 111 DROP COLUMN deleted_at + 对应索引（110 已部署但 maintenance 首跑在次日 02:00，此时尚无业务数据在依赖软删除） ### 前端重构：feature flag 声明式 + 复用 AppSidebar.vue 里 7 处 `...(flag ? [item] : [])` 样板代码删光，改为 NavItem 加 featureFlag?: () => boolean | undefined 字段，加一个 applyFeatureFlags 递归过滤（含 children）。语义统一为 `!== false`（宽容策略，undefined 时默认显示，避免 public settings 未加载完成时菜单闪烁消失 — 对应用户反馈"刷新后菜单消失要去保存设置才回来"）。 - 集中声明 4 个 flag getter：flagChannelMonitor / flagPayment / flagOpsMonitoring / flagAdminPayment - 提取 buildSelfNavItems 复用用户端主菜单和管理员"我的账户"子菜单 - 未来新增开关：在统一位置加一个 flag getter + 给对应 NavItem 加字段（不用再动渲染逻辑） bump 0.1.114.29
