Subject: [PATCH] feat(sub12c): chronological CoC body + body_style opt-in
 router (Task 3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New template: fusion_plating_reports.coc_body_chronological.
Walks fp.job.step.move records in time order (chain-of-custody).
Per-move heading 'Step Name (Tank Code)' with 'Moved By / Time / Qty'
meta line + a 5-column measurement sub-table (Name / Description /
Target / Actual / Recorded By) when the destination step has captured
inputs. Heading-only when there are no inputs (gating moves).

New router template: coc_body_router. Picks chronological vs classic
based on fp.certificate.body_style. Existing certs default to 'classic'
so no regressions. Both English + French CoC templates rerouted.

fp.certificate.body_style ('classic' | 'chronological') exposed on
the cert form alongside certified_by_id. Operator picks per cert.

Sign-off block reuses the existing owner_user_id signature pattern +
x_fc_coc_signature_override fallback. Cert statement boilerplate is
inline (Sub 12d will move it to a configurable per-customer field).

The Actual column in the measurement sub-table is rendered blank
because Sub 12a/12b runtime captures step_input values via the
operator's per-step input form which lives in a model not yet wired
into this template — Sub 12d follow-up.
