refactor(docker): switch to node:24-bookworm-slim base image

Replace debian:bookworm-slim with node:24-bookworm-slim to:
- Use latest Node.js 24 LTS and npm
- Fix npm version compatibility issues (npm@11 requires node >=20.17)
- Simplify Dockerfile by removing nodejs/npm installation
- Better optimization from official Node.js image

Changes:
- Dockerfile.full: use node:24-bookworm-slim base
- Remove nodejs, npm installation steps
- Remove npm upgrade step (included in base image)
- Update Makefile descriptions to reflect Node.js 24
