dataforth/dsca33-45: recover lost specs from Hoffman API (56/58 models)

The DSCA33/DSCA45 main spec files lost in the cryptolocker wipe are recoverable:
the original software published correct certs to the Hoffman product API before
the wipe and our null-skipping renderer never overwrote them. Mine per-model
Final-Test templates (names + specs + verbatim accuracy headers) straight from
those originals instead of requesting spec files from Dataforth/John.

- dsca33-45-templates.json: 56 models (DSCA33 34/35, DSCA45 22/23); only
  DSCA33-1948 + DSCA45-1746 (24 units) lack an original.
- mine-hoffman-dsca.py: the re-runnable miner.
- DSCA33-45-HOFFMAN-RECOVERY handoff for the AD2 session (incl. the gate:
  validate each render vs its Hoffman original before enabling live rendering).
- memories: Hoffman recovery (supersedes the spec-gap "need John" note) and the
  AD2 SSH MTU-blackhole root cause/fix; errorlog entries (syncro jq, ssh correction).
