Fix det_diff's Jungfrau id: JF07T32V01 -> JF01T03V01 (stale vs. live config)

bernina_config.json (the live, persisted config_bernina store) has both
xrd_config.jfs and robot_config.jf_id/jf_name saying det_diff is
JF01T03V01, but bernina.py had it hardcoded to JF07T32V01. Confirmed
JF01T03V01:roi_intensities is currently live on the dispatcher while
JF07T32V01's is not -- the physical detector assignment moved and this
hardcoded id never got updated.
