Refactor Supabase services in docker-compose.yml for better organization and testing

- Commented out all Supabase services to facilitate testing with Supabase CLI.
- Updated README to include Supabase directory in project structure.
- Adjusted documentation for migration paths in Supabase Docker Compose guide.
- Enhanced docker-compose-reset.sh to explicitly remove Supabase volumes and wait for migrations to complete.
