Replace an operator fixed-width layout template

Fully replaces a stored per-tenant fixed-width layout template (records/fields/discriminator/recordWidths/requiredFields) by its id — a PUT full replace, not a sparse patch, since the byte-range invariants are whole-layout properties. The replacement is run through the SAME well-formedness gate the submission path enforces BEFORE storage: overrun, overlap, missing-required, zero-field, or a mis-marked money column (money MUST be kind=decimal) rejects with 422 and the stored template is left unchanged. Returns 404 when no active template matches, 409 when the new format key collides with another active template. Tenant from the JWT; never the body.
