Fix occasional UAF crashes in KConfig::sync() during exit
Previously, c035e95 introduced `QtConcurrent::run` to execute `KConfig::sync()` in a separate thread. However, this introduced thread-safety issue:
BUG 518433 (UAF caused by RC):
During application exit, the main thread frees the old `s_sessionConfig` in `KMWSessionManager::saveState()` to create a new one. Meanwhile, the worker thread is still iterating over the old instance's entryMap during `KConfig::sync()`, leading to a Use-After-Free (UAF) crash.
Changes:
Copy the `config` in the main thread so `KConfig::sync()` can safely run in the worker.
