Migrate web app from Python/FastAPI to Node.js/TypeScript

Replace the entire Python/FastAPI backend with a Node.js/TypeScript stack:
- Framework: Hono + @hono/node-server
- Templates: Nunjucks (.njk) replacing Jinja2 (.html)
- ORM: Drizzle ORM with mysql2 (same MariaDB schema, no migrations needed)
- Sessions: hono-sessions with CookieStore
- CSS: Pico CSS v2 replacing Bootstrap 5 (Bootstrap Icons CDN kept)
- Dev: tsx watch; Prod: tsc + node dist/index.js

Original Python app preserved in web-python/ as backup.
Updated Dockerfile.web and docker-compose.yml for Node.js deployment.
