Currently, users are unable to add or remove pages from an existing campaign once it's created. We need to add functionality that will allow the user to add or remove pages dynamically, even after the campaign is created. This can be done by providing options to turn pages on or off within the campaign, and also allow users to remove individual pages if necessary.

The following pages can be added or removed:

• Landing Page
• Result Detail Page
• Opt-in Page
• Claim Page
• Validate Page
