Subject: [PATCH] fix: free default ubuntu uid/gid before creating astrai user

- ubuntu:24.04 base image ships a default 'ubuntu' user/group at uid/gid 1000, so the default USER_UID/USER_GID build args collided and docker build failed at groupadd with "GID '1000' already exists"
- remove the default ubuntu user/group first (tolerating images without it) so the astrai non-root user is created with the host uid/gid as intended
