openalex.fetch_paper fills paper.id from OpenAlex's URL-form doi/id
(e.g. https://doi.org/10.48550/arxiv.math/0603097), and ingest upserted that as
papers.id. Live DB confirmed 35/36 ids were URL-form — breaking bare-id lookups
(graph related / discover citing / search by id) and leaving cited_id matching
to rely solely on openalex_id.
ingest now sets paper.id to the caller-supplied id (the arXiv id / DOI the CLI
and ingest scripts use); OpenAlex's work id is retained as openalex_id and in
paper_identifiers. Regression test: fetch_paper returns a URL-form id, papers.id
upsert uses the bare caller id.
T-3: the OpenAlex test fixture used a bare 'doi' (not the URL form the API
emits) and never asserted paper.id, which masked this. Fixture now uses the URL
form and the test pins fetch_paper's mapping.
NOTE: existing rows keep their URL-form ids until re-ingested — run ingest_all.sh
to migrate the 36-paper corpus (chosen migration path).
