Handle stuck-frame retries before job.autoEat.

When job.autoEat is true, line 975 returns EATEN before this branch executes. A status-303 frame with retries remaining is then not retried. Move the stuck-frame condition before the auto-eat branch and add an auto-eat regression test.

around lines 985 - 987, Update FrameCompleteHandler so the
EXIT_STATUS_FRAME_STUCK condition in the report handling executes before the
job.autoEat branch, returning WAITING when retries remain. Add a regression test
covering an auto-eat status-303 frame with available retries and verify it is
retried rather than marked EATEN.
