chore: ship the full working frontend + backend

The crates.io/release build shipped a STALE frontend (committed web/js was behind
the working tree), so the admin console hung on load. Commit the current working
web/js (app, api, dashboard, login, import view, i18n de/es/fr/tr/zh, css) and the
backend WIP (import.rs, admin/assets.rs) so the released console matches the dev
build. Verified: clean `cargo build --release`, empty-pool start, working
dashboard served.
