Improve display of regenerated images

When regenerating an image (whether by modifying parameters, models or settings), instead of generating new responses as separate messages, it would be optimal to implement an interactive carousel that groups all the variants in a single view. This system would allow horizontal swiping to compare versions, avoiding cluttering the interface, and would automatically maintain the metadata associated with each image (model used, prompt, seed, technical settings, etc.), which would facilitate analysis, replicability and creative decision-making.
