dataforth(datasheet): Fix 2 STAGE 3 — DSCA render validator + first full report

validate-dsca-stage3.js: read-only harness that, for every staged DSCA original
we have ground truth for (2806 across 126 models), looks up the DB record,
renders it through the live path, and content-compares. GATE = the FINAL TEST
RESULTS section (rule lines canonicalized, whitespace collapsed — so the deferred
column-spacing cosmetic doesn't register); accuracy-section diffs reported
separately as informational.

First run verdict (report attached):
- 68 models FINAL-TEST CONTENT-CLEAN (0 mismatch over compared certs).
- 2123/2316 certs match the Final-Test content exactly (91.7%).
- 26 models show measured-value last-digit diffs only — structure (names, specs,
  row alignment, statuses) is correct. Two root causes, neither structural:
    * rounding-mode: JS double toFixed vs QB single-precision half-up
      (e.g. raw 9.9995 code3 -> "9.999" here, "10.000" in golden). Fixable but
      float-precision-sensitive; risks regressing currently-clean values.
    * data vintage: staged .TXT is a different test run than the DB latest-wins
      record (Fix 3) — e.g. Supply Current 19.6 vs 20.3, 0.7 apart. Not a render
      bug; can't be reconciled against an older staged sheet.
- ~32 models render null (count-guard): DSCA33-*, DSCA45-*, DSCA49-* families
  whose raw_data carries load points the template omits -> need per-subtype slot
  mapping (the canonical-slot approach) before they can render.

Still NOT published: service not restarted, nothing re-pushed to Hoffman.

Fix 2 STAGE 3 — DSCA Final-Test render vs staged-original content validation
GATE = FINAL TEST RESULTS section, content-strict (rule lines canonicalized,
whitespace collapsed). Accuracy-section diffs reported separately (deferred
cosmetic spacing + any pre-existing calc rounding — NOT a Fix 2 gate).
Corpus: 2806 staged DSCA originals across 126 models.
