openai: wire Adolf OpenClaw gateway on Matrix [Adolf P6]

Build adolf:local with the matrix extension bundled (OPENCLAW_EXTENSIONS),
route mtx.alogins.net to host-gateway to dodge hairpin NAT, and wire
ADOLF_KEY/Matrix creds through openai/.env (now gitignored + untracked;
it previously held Langfuse keys in cleartext git history). Runtime
openclaw.json + SOUL.md live in the adolf-state volume, not this repo.
