// ---------------------------------------------------------------------------
// 覆盖目标：UpdateProfileWithTx 的 pre-commit DelCache 窗口闭合。
//
// 修复前（交错）：
// T0: UpdateProfileWithTx 调用 m.ExecCtx(fn, idKey, usernameKey)
// go-zero 的 CachedConn.Exec 在 fn 成功返回时**立即**走 DelCache 两把 key。
// T1: 事务还没 commit；并发 goroutine 的 FindOne 触发 cache-miss → 回 DB 读**旧行**
// （此时事务未提交，MVCC 仍给它看到旧值）→ 再灌回缓存 = stale 值。
// T2: 事务随后 commit；新值落库但缓存已是被"回灌的旧值"，直到 TTL 到期前所有
// FindOne 都读到 stale 行。
//
// 修复后：
// * UpdateProfileWithTx 改走 session.ExecCtx 绕过 CachedConn 的 DelCache 语义，
// 事务成功与否都不去动 sysUser 的两把低层缓存。
// * 新增 InvalidateProfileCache(id, username) helper，由调用方**在 TransactCtx
// 返回（commit 成功）之后**显式调 DelCacheCtx 失效 id / username 两把 key。
//
// 本测试组把两个语义契约各自钉死：
// A) 事务内 UpdateProfileWithTx 自身不得碰缓存（即便事务 commit 成功，缓存仍持旧值）。
// B) InvalidateProfileCache 必须一次性失效 id / username 两把低层 key。
