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.
