Smooth login music start and lower auth-screen volume

Browse source 
Add configurable fade-in support to MusicManager playback paths and use it for auth/login intro tracks to avoid abrupt starts. Apply a login-only 20% music attenuation while the auth screen is active, then restore the previous music volume when leaving login so in-game volume remains unchanged.
