Mike Swanson 3372455b79 dataforth(datasheet): Fix 2 — data-driven DSCA load note (fixes DSCA39 footer artifact) ...

Root cause of the DSCA39 footer mismatch: the "Standard output load for test is
250 ohms." line is a footer note, not a parameter, but the STAGE 1 extractor
captured it as a (column-truncated) row "Standard output load for te". And the
renderer's OUTSIGTYPE==='CURRENT' emission was wrong on both ends — it printed the
note (after the underline, invisible to the validator gate) for many -C current
models whose staged originals never had it, and never placed it correctly for the
models that do.

Fix is data-driven, matching the rest of the template approach:
- derive-dsca-templates.js: detect the "Standard output load..." line, capture it
  as a per-model `loadNote` property, and exclude it from rows. Regenerated
  dsca-templates.json — surgically clean: only the 5 DSCA39 models changed (lost
  the truncated row, gained loadNote); all 121 others byte-identical.
- datasheet-exact.js: emit `dscaTpl.loadNote` (blank line + note) before the footer
  underline, only for models that have it; removed the OUTSIGTYPE-based emission.

STAGE 3 re-validation: FINAL-TEST CLEAN 85 -> 88, mismatches 9 -> 6, matches
2206 -> 2278. DSCA39-01/02/07 now fully clean; DSCA39-01 byte-content-verified.
No regression — the -C current models stayed clean and no longer carry the
spurious after-underline note.

The 6 remaining dirty models (DSCA38-05/-1793/-19C/-19E, DSCA39-05, DSCA39-1950)
are ALL retest data-vintage: the staged .TXT is an older test run than the DB
latest-wins record (Supply Current / Linearity differ by more than rounding).
Not render bugs — cannot be reconciled against an older sheet.
