fix: widget modal — clean embed mode, better close button, backdrop blur

- ?embed=true renders widget without page wrapper (white bg, no padding)
- widget-loader.js appends &embed=true to modal URL automatically
- Close button is now inside dialog (not overlapping iframe), light style
- Backdrop blur effect, Escape key closes modal
- FAB: subtle translateY on hover instead of scale
