Improve privacy and UX for public feed controls

Privacy improvements: - Removed email address from episode page
signup banner - Changed 'This episode was created by <email>' to
'This episode was created using PodcastItLater' - Protects user
privacy while still showing the signup prompt

Admin UI improvements: - Removed floating Public/Private toggle
button (was confusing) - Added '+ Add to public feed' button at
bottom of episode cards - Button only visible to admin users - Shows
'Added to public feed' with checkmark when already public - Shows '+
Add to public feed' with plus icon when private - Clearer and more
actionable UX for managing public feed content
