feat: containerize for mmd.i80.dk deployment via Gitea/Nomad

- Add Dockerfile (python:3.12-slim, HF_HOME=/app/data/hf-cache)
- Add mmd.nomad (multi-task: web=dashboard, worker=scheduler)
- Add .gitea/workflows/deploy.yml (build->Harbor, deploy->Nomad)
- Add scheduler.py (stdlib scheduler replaces cron in container)
- Add requirements.txt
- dashboard.py: LOG_DIR + PORT/HOST from env vars
- saxo_auth.py: TOKEN_FILE from SAXO_TOKEN_FILE env var
- .gitignore: proper ignores for container project

Volume moneymaker-data (/app/data) holds:
  - logs/ (shared between web+worker)
  - .saxo_token.json (pre-copy once after first deploy)
  - hf-cache/ (HuggingFace FinBERT cache)

Gitea secrets required: DATABASE_URL, ANTHROPIC_API_KEY,
SAXO_APP_KEY, SAXO_APP_SECRET_1, HARBOR_ROBOT_TOKEN
