Jake Dallimore 59b5858da2 MDL-73736 core_auth: Fix concurrency issue in login_attempt_failed()
This patch wraps the login_failed_count logic in a resource lock and
forces a user preferences cache reload. Each thread must wait for the
lock and must fetch the current count before incrementing it. This
ensures that login_failed_count is correct across threads and that the
lockout threshold is correctly honoured.
