Increase maximum characters in text prompt box for generating videos #296

Please increase the maximum characters in the text prompt box for generating videos. If one works with more complex AI video models like Wan 3.0 and is in need of lenghty, complex text prompt instructions for 30 second clips, the current limitation of characters of 3000 characters including spaces is simply not enough. It would be highly appreciated to increase the maximum of characters including spaces, up to 6.500.
