remove: eliminate client-side progress bar system

Removes the client-side JavaScript progress bar implementation and
related assets. This prepares for migration to server-side rendering
and simplifies the client-side codebase.

Removes the JSON API generation from justfile build process since
content is now generated dynamically via the mdbook preprocessor.
Simplifies the build pipeline.
