fix: widget embed — full-width support + one-liner script tags via hosted loader

- Standalone page: ?width=full removes max-w-lg container constraint
- iframeSnippet: passes &width=full to URL when 100% width selected
- public/widget-loader.js: hosted script, reads data-* attrs, no inline code needed
  - data-mode="floating" → styled FAB button bottom-right
  - data-mode="trigger"  → listens for .hotelsync-book class clicks
  - Proper modal with close button and backdrop click
- Code tab snippets for floating/trigger are now single <script src> lines
