https://perconadev.atlassian.net/browse/PS-11143 Guard caching_sha2_password entry points during plugin shutdown so auth/cache accesses drain before the singleton is destroyed. This avoids use-after-free on the rwlock-backed password cache in in-flight authentication paths, including threadpool worker threads. Also simplify the lifecycle bookkeeping by keeping it in one small file-scope state object and using the existing scope guard helper for cleanup.
