Give SexType/SpeciesType built from IRIs a name; allow dandischema 0.15.x

[yarikoptic-gitmate]

Prepares dandi-cli for dandi/dandi-schema#444. That PR makes name required (and non-empty) for Contributor and for every BaseType subclass (SexType, SpeciesType, …), with schema version 0.8.1.

Changes

extract_sex (dandi/metadata/util.py)

• When NWB subject.sex is an IRI, this produced SexType(identifier=<iri>, name=None), which would no longer validate (as noted in the review of #444).
• It now maps the two PATO IRIs this function itself emits back to "Male"/"Female". Any other IRI is used as its own name.
• It no longer lowercases the IRI: http://purl.obolibrary.org/obo/PATO_0000384 used to become .../pato_0000384.

extract_species

• For an NCBITaxon IRI that is not in species_map, the name came from an ontology lookup and was None when the lookup failed (ConnectionError) or found no label.
• It now falls back to the IRI itself.

Pin: dandischema < 0.15.0 → < 0.16.0, so that the release carrying #444 can be installed.

• Simplify release workflow #444 keeps schema 0.8.0 as an allowed migrate() target, so the downgrades this client relies on for older Archive servers still work.
• If maintainers prefer to bump the ceiling only once that release exists, the second commit can be dropped.

Tests

• New tests (marked @pytest.mark.ai_generated):
  • test_extract_sex: letter codes, the PATO IRIs, and an unknown IRI.
  • test_species_unknown_iri_lookup_fails: the ontology lookup is monkeypatched to raise ConnectionError.
• dandi/tests/test_metadata.py passes against dandischema from Simplify release workflow #444's head (166 passed, 1 skipped) and against current dandischema master (-k "sex or species": 46 passed).
• pre-commit hooks pass.
