deploy via Gitea CI registry; provision GCP infra with Terraform

- Terraform: e2-micro VM (us-east1-b, free tier), static IP, SSH/web
  firewall rules, IAM bindings for Firestore + GCS; imports existing
  drb-calls bucket and c2-server Firestore database into state
- Gitea CI: build c2-core, discord-bot, frontend images and push to
  git.vpn.cusano.net registry; SSH deploy pulls pre-built images (no
  build on VM)
- Ansible: first-time setup only — git clone, env files from vault,
  Caddyfile, docker login + compose pull + up; no rsync or on-VM builds
- docker-compose: add image: ${REGISTRY}/name:latest alongside build:
  so local dev and CI registry both work
- gitignore: add Terraform state, lock, tfvars, ansible secrets
