fix(wm): add cmd thread lock acquisition timeouts

After some investigation by @alex-ds13 on Discord it looks like there
are times where attempting to gain a lock on the WindowManager inside of
read_commands_uds results in the thread becoming blocked when it's not
possible to obtain the lock.

Instead of waiting indefinitely for a lock, this change ensures that we
will wait for at most 1 second before discarding the message so that the
command listener loop can continue.

Warning logs have been added to inform when a message has been dropped
as a result of lock acquisition failure.
