feat: implement professional modal editing forms (Phase 1.2)

MAJOR UX IMPROVEMENT: Replace basic prompt() with professional forms

New Features:
- Professional modal overlays with backdrop and ESC/click-outside cancel
- Dynamic form generation based on content type and HTML element
- Smart field detection: H1-H6→text, P→textarea, A→link with URL
- Mobile-responsive form positioning and widths
- Complete CSS styling with focus states and transitions
- Proper save/cancel event handling

Technical Implementation:
- Created lib/src/ui/form-renderer.js with modern ES6+ modules
- Integrated into core editor.js with form renderer instance
- Support for text, textarea, markdown, and link field types
- XSS protection with HTML escaping
- Responsive design: mobile-first form sizing
- Professional styling matching prototype quality

Before: Basic browser prompt() for all editing
After: Content-aware professional modal forms

This brings the library from proof-of-concept to professional-grade
editing experience, closing the major UX gap with the archived prototype.

Phase 1.2  COMPLETED - Next: Authentication system (Phase 1.1)
