feat: add production deploy pipeline and fix dev CSS

Dev:
- Add tailwind install + build to docker-compose startup so CSS is built
  inside the container — not dependent on local filesystem

Production (docker-compose.prod.yml):
- Gunicorn on 127.0.0.1:8001, bind-mounted static/media to host paths
  so Caddy can serve them directly
- Runs migrate, tailwind build, collectstatic on startup

Settings (production.py):
- Disable SECURE_SSL_REDIRECT (Caddy handles redirects; Django would loop)
- Add CSRF_TRUSTED_ORIGINS for nohypeai.net

CI (.gitea/workflows/ci.yml):
- Add push-to-main trigger
- Add deploy job: SSHes to lintel-prod-01 as deploy, runs deploy/deploy.sh

Server config (deploy/):
- deploy/caddy/nohype.caddy — Caddy site config for nohypeai.net
- deploy/sum-nohype.service — systemd unit for the compose stack
- deploy/deploy.sh — deploy script (pull, build, restart)

One-time manual steps required on lintel-prod-01 (need root):
  sudo cp deploy/sum-nohype.service /etc/systemd/system/
  sudo cp deploy/caddy/nohype.caddy /etc/caddy/sites-enabled/
  sudo systemctl daemon-reload && sudo systemctl enable sum-nohype
  sudo systemctl reload caddy
