- Replace nginx with Node.js server that serves static files AND
provides API endpoints for reading/writing maps.js directly
(GET/PUT /api/maps). Creates .bak backup before each save.
- Editor: arrow keys to pan, +/- to zoom, Ctrl+S to save
- Editor: "Save" button writes maps.js directly on the server
- Editor: "Load" button reads and parses maps.js from server
- Editor: auto-loads from server on page open
- Dockerfile changed from nginx:alpine to node:20-alpine
