chore: merge main and update root pydantic constraint to >=2.13.4

The root pyproject.toml constrained pydantic to <2.12.0. Updated to
match the ogx_api sub-package requirement of >=2.13.4 and regenerated
the lockfile and OpenAPI specs.

Note: the API spec breaking changes check fails because pydantic 2.13.4
generates different OpenAPI schema shapes (anyOf/oneOf serialization).
This needs review to confirm the changes are cosmetic and not actual
API contract breaks.
