- Remove clunky multi-property editor with separate text + URL inputs
- Implement single rich text editor (contentEditable) for all content
- Add popup-based link configuration: select text → click 🔗 Link → configure
- Filter out link styles from formatting toolbar (links use popup, not buttons)
- Consolidate CSS: remove separate style-aware-editor.css, integrate into insertr.css
- Clean up 200+ lines of unused multi-property form code and styles
- Fix duplicate link style detection (no more 'Fancy Link' + 'Link' buttons)
Result: Much cleaner UX similar to modern editors where formatting uses
toolbar buttons and complex elements (links) use dedicated popups.
