FEAT: Add script generation to 'Generate script with AI' tab

[o-nedashkivska]

What feature?

On the video modal component there is 'Generate script with AI' tab. When a user fills form and click 'Generate script' button, the script must be generated (using chat controller) and placed on the right side of the tab (see https://heygen.com/ for reference).

For now chat controller accepts only message property, so make a helper that creates one single message from all fields on the form (e.g 'Please generate script on topic [topic from the form] in [language from the form] ...').

When script is generated change button text to 'Regenerate'. If user click on 'Regenerate' button regenerate the script (e.g. send message to chat 'Please, generate another script from the info I have provided before').

When script is generated place 'Create video' button under the script. The button should not do anything for now.

Use HeyGen as a reference but apply our app colors.
