Add production deployment, photorealistic movement walls, and fix duplicate influence links.

Configure hosting for gallery.mysuperlab.netcraze.pro and LAN access, enhance movement gallery textures with period-appropriate painted materials, dedupe influenced-by API responses via painting_influence_sources, and refresh several painting image files.

 ```bash
-npm run server    # http://localhost:3001
+npm run start:prod   # build client + serve on PORT (default 3520)
+# or: npm run build && npm run start

 ### Development (two processes)
 
 ```bash
-npm run dev:server   # API on :3001
-npm run dev:client   # Vite on :5173, proxies /api and /images
+npm run dev:server   # API on PORT from .env (3520 production, 3001 typical dev)
+npm run dev:client   # Vite on :5173, proxies /api and /images to PORT
