- autogen page.js: wrap engineCall in try/catch (return null on any failure)
- /zero page: use Promise.allSettled so one failed source doesn't break page

Root cause was ENGINE_URL=host.docker.internal not resolving in coolify net,
fixed at env level but defending code too so future quirks degrade gracefully.
