Carry a document's families as a bundle, not as one struct of typed arrays

`curve_configuration_document` carries the curve configuration file as one struct of 34 typed vectors, each a full domain type: the root configuration, its sections, definitions, nine kinds of curve, six kinds of volatility configuration, the reports, the bootstrap configurations, the segments and the quotes. It is the largest message in the tree, and its translation unit is the one that fails the Windows build.

The classifications call this shape what it is: an aggregate list of entities in one struct is a second type system and is forbidden, because the generator cannot see it and the compiler pays with a diagnostic that names no field. That is exactly the nightly failure: `C1202` inside `rfl/internal/no_duplicate_field_names.hpp`, reached from `reply<get_curve_configuration_document_response>`, naming nothing.

The families here are related — every one of them hangs off `curve_definition_id` — so the set is a bundle, and the bundle is not a message shape. Per the classifications: a bundle's verbs are its families' operations, and its rows never sit in a message field. Where the bytes must still travel as one ORE file, that file is a package: a modelled manifest of references and a content-addressed archive of msgpack parts, with a coordinator that sends one message per bundle carrying the archive URI and never the data.

The precedent to avoid is `conventions_bundle`, whose `std::string payload` holds JSON in a staging row. That is the import staging path, not the wire shape, and it is not the model to copy.

• The curve configuration document is a bundle: one generated `ores.codegen.family` operation per family, each with its own protocol.
• The ORE boundary carries it as a package: a modelled manifest of references, an archive of msgpack parts, and a coordinator that sends one message per bundle with the archive URI.
• The Windows nightly compiles without the C1202, proven by the job rather than by argument.
• No struct in the tree carries a typed array per kind.

• `doc/knowledge/architecture/data_classification.org` — the anti-pattern and the decision rule.
• `doc/knowledge/architecture/package_transport.org` — manifest, parts and coordinator.
• `doc/knowledge/architecture/data_oriented_design.org` — the accumulation path, which is why the handler fails while the entity compiles.
• Windows nightly run `40457388317` — the failure this removes.
• `projects/ores.refdata/modeling/ores.refdata.configuration_document_messages.org` — the model that produces the aggregate.
