[Product Quality] Edit feature

[kidroca]

Sometimes we want to edit a chapter - manually or automated to:

• edit some typos
• change character names
• generate more content
• or just rephrase stuff the way we want to

Also we want to be able to re-generate a specific chapter image:

• we want to either re-generate
• update the illustration instructions (prompt) and re-generate
• or just upload an image of our own
• or specify a remote url (that will be downloaded behind the scenes)

It would be great if there's an edit button, that changes the chapter to edit mode where we have some controls to re-generate the story, edit the content manually or provide instructions on how the AI should try and shape it

Also an edit button to change the title or to generate a new one
