test(docs): the order fields stand on all five surfaces (red)

order_id / order_claimed_at / order_reason on the five surfaces: (1) record
format = the writer (pinned in stats-landing), (2) Phase 7 prose with "the
writer adds", (3) the field-allowlist header names them as dropped and
TREKBRIEF_ALLOWED leaves them out, (4) the trekbrief-stats fixture row's
`fields` column + EXPORT_DENYLIST, (5) docs/architecture.md Stats. Plus: the
row's line_ref must contain the Phase 7 stats-append line (it said 657-672,
the line is at 958); /trekbrief --approve reaches Phase 7 with mode "approve"
(PM 04.10, point 3) and CLAUDE.md, README.md, docs/command-modes.md say so.

Red: 7 doc pins fail. Green on arrival: the yardstick-header pin (Step 6
already rewrote the header) and the otel DROP guard (the fields were never
allowlisted).
