The version string was duplicated across six places. Collapse it to two
ecosystem sources of truth and derive the rest:
- backend/src/web_server.rs: omit the OpenAPI info.version so utoipa fills
it from CARGO_PKG_VERSION (backend/Cargo.toml); add a test pinning this.
- nix/package.nix: read the version from backend/Cargo.toml via fromTOML.
- nix/frontend.nix: read the version from frontend/pubspec.yaml by splitting
into lines (a whole-file regex triggers catastrophic backtracking in Nix's
regex engine).
- frontend/lib/about/about.dart: read the version at runtime via
package_info_plus instead of a hardcoded constant.
Also drop frontend/pubspec.lock.json: it is unreferenced (Nix's
autoPubspecLock generates its own JSON from pubspec.lock) and was going stale.

- Replace single NavigationRail with adaptive navigation: NavigationBar
(bottom) for compact <600dp, icon-only NavigationRail for medium
600–840dp, and extended NavigationRail for expanded ≥840dp
- Remove nested Scaffold/AppBar from About, Settings, DeviceList, and
DeviceDetail — all screens now render as plain widgets inside the
single shell Scaffold; page titles surface as inline headings

Implements the /about route with app description, version info,
clickable links to the source repo and AGPL-3.0 license, and
third-party copyright notices. Adds url_launcher for cross-platform
link handling.
