chore(deps): pin openapi-python-client to patched fork branch

Adds a [tool.uv.sources] override resolving openapi-python-client from
alexander-wenzel-dev/openapi-python-client at branch
pin/mealie-mcp-combined. The branch carries two unmerged generator
fixes (upstream PRs openapi-generators/openapi-python-client#1448 and
openapi-generators/openapi-python-client#1449) that unblock the
Recipe-Input / Recipe-Output models and the PUT/PATCH recipe endpoints
in the generated client.

This commit only changes resolution; the generated client tree is
untouched and gets regenerated in a separate PR. Removal plan is
inline in pyproject.toml.
