fix(civitai): add nsfw param to user-models and batch-ids queries (#930)

The CivitAI /api/v1/models endpoint defaults to filtering out NSFW
content when the nsfw query parameter is omitted. Both get_user_models()
and get_model_versions_bulk() hit this endpoint without passing nsfw=true,
causing models whose nsfwLevel doesn't include the PG bit to be silently
dropped from results.

Add nsfw=true to both call sites so all browsing levels are returned.
