Raw-series ordering schema metadata compatibility

v1_metadata.json is a hand-authored, frozen set of Arrow schema metadata maps for the v1 raw-series frame. It records the established layout/content/labels/ time metadata and the new optional ordering entry. The Rust unit test parses these literal maps through raw_series_frame_ordering; the fixture is not produced by the schema builder.

Run the focused check:

cargo nextest run -p common-query -E 'test(raw_series_ordering_metadata_fixture)'

The fixture proves that absent ordering metadata defaults to Contiguous, the two known values decode, and an unknown value is rejected. It does not prove interoperability with an old binary, nor does it test an end-to-end client or service. Separate pack/IPC tests check the declared ordering schema and batch schema agreement for both orderings, including empty streams.
