chore: sync schema from live Deezer API

Regenerate schema.graphql/schema.json from pipe.deezer.com. Changes are restricted-access DeezerClub/RemixContest features and a raw-favorites refactor; no consumed Artist/Track/Query/Mutation types changed, so the generated client is unaffected. Also reconcile uv.lock with pyproject (ruff 0.15.16, pytest-asyncio 1.4.0).
