Same pattern as the gateway (a54fdcb): the mp-suppliers-* DNS records are no
longer Cloudflare-proxied, so each supplier gets a websecure router with the
letsencrypt resolver and its :80 router becomes a permanent HTTPS redirect.

Adds an optional OPENAI_API_KEY env var that supplier/src/openai.ts forwards as
`Authorization: Bearer <key>`. Empty/unset preserves the ChatMock behaviour
(no auth header). Unlocks pointing the openai backend at DeepSeek directly
(https://api.deepseek.com) — no local proxy needed.
New compose: deploy/mainnet/docker-compose.supplier-deepseek.yml (third mainnet
supplier, model deepseek-v4-pro, mp-suppliers-deepseek.vector.apexfusion.org).
