refactor: make optimized Dockerfile the default - remove full variant

- Rename Dockerfile.optimized to Dockerfile (now the default)
- Keep old Dockerfile as Dockerfile.old for reference
- Update GitHub Actions to use default Dockerfile
- Remove build-full job - only one image variant now
- Remove docker-compose.optimized.yml and other variants
- Update all documentation to reflect single image approach

The optimized 283MB image is now the only n8n-MCP Docker image.
This simplifies the user experience and provides the best solution
for all use cases.
