Fixes #11394

The Seedream 4.5 model supports up to 4704×4704 resolution, but the node was
limiting it to 4096×4096.

Changes

  • Updated UI schema max values for width/height to 4704
  • Added model-specific validation so Seedream 4.0 remains at 4096 max
  • Seedream 4.5 now correctly allows up to 4704×4704

Backward Compatibility

  • Seedream 4.0 behavior is unchanged (still limited to 4096)
  • Only relaxes constraints for Seedream 4.5 to match model capability
