Unify Node version contract between Docker and CI

Dockerfile builds the web-builder stage with FROM node:26-slim, while .github/workflows/ci.yml runs the web job on Node 22 (node-version: "22"). Additionally, web/package.json pins @types/node to ^22.10.2, so CI and Docker are using different Node/type baselines—creating a real validation gap for Node-version-specific issues.
