chore: remove Hetzner legacy artifacts and update docs for Mac Mini self-hosting

Deleted files:
- docker/caddy/Caddyfile.production + Caddyfile.staging (Hetzner reverse proxy configs)
- scripts/deploy/ (deploy-hetzner.sh, build-and-push.sh, health-check.sh, migrate-db.sh, rollback.sh)
- scripts/generate-staging-secrets.sh
- cicd/ directory (11 Hetzner CI/CD planning docs)
- CI_CD_IMPLEMENTATION_SUMMARY.md, CI_CD_README.md, FILES_CREATED.md, HIVE_MIND_FINAL_REPORT.md

Updated docs:
- CLAUDE.md: Remove Hetzner Object Storage references, update to MinIO
- docs/ANALYTICS.md: Cloudflare Tunnel instead of Caddy
- docs/URL_SCHEMA.md: Mac Mini + Cloudflare Tunnel instead of Hetzner IP
- .env.development: Remove "Hetzner in production" comments
