Per-citation CMS nursing-home deficiency list for a facility.

Each row is one Health Deficiency citation from CMS Care Compare --
survey date, deficiency tag (F-tag), the textual description,
scope-severity letter (A-L), whether corrected, and the inspection
cycle (standard survey vs complaint vs infection control).

Lookup: resolves cms_ccn from employer_profile. Only facilities with
a populated CMS Certification Number have deficiency rosters. Other
employers return 200 with empty results.

Severity coloring at the UI layer follows CMS conventions:
  A-C: isolated potential harm (mild)
  D-F: pattern potential harm (moderate)
  G-I: actual harm (high)
  J-L: immediate jeopardy (critical, burnt-umber)

Ordered most-recent-survey first, then severity within survey.
