fix: reliability fixes for UHC SCO and CMSP eligibility checks

- unitedSCOEligibilityProcessor: overwrite patient's stored insuranceId when
  the eligibility page reports a different (updated) Member ID than the one
  searched with.
- CMSP worker: add AngularJS late-binding retry to results-table extraction
  (ported from the MH worker's a0417653 fix), since every patient now routes
  through this worker for the accumulator check.
- cmspEligibilityHistoryRemainingProcessor: stop forcing patient status to
  UNKNOWN when extraction fails; a failed run landing after a successful one
  was clobbering a correct ACTIVE/INACTIVE status.
