kert 16e006fb5e fix all cclf transpile errors: pivot rewrite, column fix, schema alignment ...

- Rewrite diagnosis/procedure pivots from 25-iteration progressive
  joins to conditional aggregation (group_by + when/then/max),
  eliminating deeply nested SQL that caused sqlglot RecursionError
- Fix clm_line_srvc_unit_qty column reference (no _rev suffix needed,
  column is unique to right side of join)
- Move _nullify_sentinel into claim_start_date/admission_date aliases
  instead of producing extra clm_from_dt column that broke nw.concat
  schema alignment across institutional/physician/DME claim types
- All transpile known failures resolved: 0 remaining
