Phase 1 — DB: adds dwdm_channel, cwdm_channel, cdr_type, protocol_family
columns to transceivers (migration 134). Backfill from Flexoptix notes:
1,209 standard_names (+1,579%), 1,177 cdr_types, 2,498 wdm_types,
7,918 protocol_families.
Phase 2 — API sync: flexoptix-api-sync.ts now writes standard_name,
wdm_type, cdr_type, cdr_support, protocol_family on every sync.
Phase 3 — Scoring: catalog-reconcile.ts adds hard rejects for
protocol_family/temp_range/wdm_type mismatches, -25pt standard_name
mismatch penalty, CDR type scoring, and requires fx.standard_name to
be set before auto_approve — closes the 77k false-positive gap.
