Move scroll animations to Rust/WASM, enable Hasura, and move bookmarks to home sidebar

Port AutoScroll and Headline scroll logic from Vue/JS to Rust compiled
to WASM via wasm-pack. Add multi-stage Docker build for WASM compilation,
Vite WASM plugins, and top-level await for WASM init. Enable Hasura
service in docker-compose. Move bookmarks from a separate route to an
inline sidebar component on the home page. Fix ToggleHeader click
propagation.
