Refactor BrandStyleManager and MarketingCopywriter to accept dependencies via constructor, enhancing testability. Update main.py to manage campaign data with new routes for saving, editing, and deleting campaigns. Improve index.html with a textarea for editing generated copy and a button for saving changes. Add functionality to view past campaigns.
