fix(config): wire cargo-leptos features and CSS source file

Browse Source 
- Add bin-features/lib-features so cargo-leptos enables ssr/hydrate
  correctly (server was exiting immediately with empty main otherwise)
- Add style-file so the CSS bundle is no longer empty
- Replace #[cfg(target_arch = "wasm32")] with #[cfg(feature = "hydrate")]
  in theme.rs to match when web-sys is actually available
