feat(profile): generated default avatars (boring-avatars beam) from pubkey

Browse source 
People without a photo or seed illustration now get a deterministic
pattern avatar drawn from their pubkey (flutter_boring_avatars, MIT),
in an earthy seed-tone palette, replacing the coloured-initial disc.
Same pubkey renders the same picture on every device with nothing shared.
