Add support for the progress bar.

This would support issue #88 - Add support for progress bar.

The progress bar implementation was great.
I updated the implementation to make it work on the editor and address some accessibility issues for consistency.

Everything works as expected—approved!

Pull request overview

Adds a new “Carousel Progress” inner block to Carousel Kit and wires it to Embla’s scroll progress so the editor and frontend can render a progress bar similar to carousel dots.

Changes:

• Introduces a new carousel-kit/carousel-progress block (block.json, edit/save, styles).
• Tracks scrollProgress from Embla in both the frontend interactivity store and the editor context.
• Registers the new block server-side for discovery/loading.
