Removing MPListenerController (cherry picked from commit 91c0c5d) * fix: Thread-safe access to currentUser to prevent crash during kit replay (#576) The currentUser property on MPIdentityApi was nonatomic with no synchronization, but written on messageQueue (via identity responses) and read on the main queue (via replayQueuedItems -> isActiveAndNotDisabled).

This preserves the original file formatting and eliminates the need for post-processing with prettier or trunk fmt.
