Public Access
Users can set a display name (shown instead of username in the message list, room member list, TopBar, and admin Users tab) and upload a real avatar, replacing the generated color-initial avatars everywhere a user appears. Avatars are square-cropped and downscaled to 512px, reusing app/storage.py's upload primitives from image uploads with a new square option. Two deliberate divergences from message-image handling, documented in backend/README.md: the previous avatar file is deleted on replace/remove (safe since it's strictly one file per user), and avatar serving is not room-gated and uses a short cache (identity-addressed and mutable, unlike a message image's permanent content-addressed URL). Frontend: new ProfileModal reachable from the TopBar account menu; AuthContext gains updateUser() so a profile change reflects instantly everywhere without a refetch.
