fix: drop seed/denoise/clip_type from schema-drift validator

These keys legitimately aren't set in pre-orchestrator configs:
- seed: filled by expand_configs (node-level seed widget or per-entry override)
- denoise: filled by run_generation_loop from the denoise widget
- clip_type: only set when model_type != "checkpoint"

The validator was a stale leftover from the pre-single-source-of-truth era.
Trimming false positives. Still warns on actual typos / dropped fields.
