fix(server): SPA history fallback — serve index.html for client-side routes

A hard navigation/refresh/direct-URL to a React Router route (/login, /settings,
…) reached the static mount as a 404. Add a set_error_handler that serves
index.html for non-API/non-meta/non-asset GET 404s. Bump VERSION -> 0.1.2.
