fix: set image format before calling write() in ImageMagick

Browse Source 
The correct API pattern is:
1. Set image.format = outputFormatEnum first
2. Then call image.write(callback) with the format already set

This ensures the image is written in the correct format with proper
headers (RIFF for WebP, etc.)
