fix API routing: remove /api prefix in Express routes

Uberspace web backend removes /api prefix before forwarding to Express,
so routes must not include /api. Changed from app.all('/api/*') to
app.all('/*').

/health route is defined first, so it takes precedence.

Fixes 404 errors when calling Steam API from production.
