feat: Update Seedream 4.5 resolution limits to 4704x4704

Browse Source 
Fixes #11394

The Seedream 4.5 model supports up to 4704x4704 resolution, but the node
was limiting it to 4096x4096. This commit:

- Updates the UI schema max values for width/height to 4704
- Adds model-specific validation so Seedream 4.0 remains at 4096 max
- Seedream 4.5 now correctly allows up to 4704x4704

This is backward compatible - Seedream 4.0 behavior is unchanged.
