erio ef6ec8a15a 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)
