Simplify slide editor by removing layout change feature and add obvious edit buttons

- Remove "Change Layout" buttons from slide editor header and content actions
- Simplify user flow: layout selection only happens once when creating new slides
- Existing slides go directly to content editing, skipping layout selection
- Add prominent edit buttons to slide thumbnails and main slide view
- Style edit buttons with blue theme to make them obvious primary actions
- Add "Cancel editing" link styled as underlined text link for clear visual distinction
- Improve responsive design for mobile with proper button spacing
- Lock in layout choice after selection to prevent confusion and content loss

Benefits:
- Cleaner, more focused editing interface
- Prevents accidental layout changes that could break content formatting
- Clear visual hierarchy with obvious edit and cancel options
- Faster editing workflow for existing slides
