/// 与 Cron job_s5_t8_kpi_refresh 共享同一把锁（<see cref="RefreshLockKey"/>），保证手动刷新与定时跑批互斥、并发手动刷新排他。
/// 入站为 S5/S6/S7 共用（T8BaseInboundMdpSyncService 6 张基表无法按模块拆），故刷任一模块均触发一次全量入站。
/// S5_L1_002 / S5_L1_004 仍 legacy 直连 T8（本轮不改），随 S5 RunFull 一并执行，逐指标标 LEGACY_SUCCESS。

/// 原因：BeginCacheLock 在持有者线程存活期间会续租，一旦某次运行意外挂死（如源库慢查询无超时）会永久占锁、
/// 阻塞后续所有刷新。改为硬 TTL 后：正常路径 finally 主动 Remove；即使挂死，键到 <see cref="RefreshLockTtlSeconds"/> 也自动过期。
/// 配合 QueryT8Async 的 T8 命令超时（60s）与主库命令超时（30s），单次运行时长恒 &lt; TTL，正常不会误过期。
