   Fixes API server memory leak when reading logs from running tasks with 
KubernetesExecutor.
   
   When the API server serves logs for RUNNING task instances, it was 
instantiating KubernetesExecutor to obtain get_task_log. Each instantiation 
creates a multiprocessing.Manager() process (~350-400 MB) that runs forever and 
is never cleaned up. This caused one leaked Manager per API worker, 
accumulating with worker refresh cycles and leading to OOMs.
   
   The fix loads the executor class without instantiation and uses the existing 
_get_task_log_static classmethod when available, preventing Manager process 
creation. Falls back to instantiation for executors without the static method.
   
   closes: #68693
