chore(security): remove committed secrets/dumps, .env-based config, hardened deploy webhook

- Delete backups/*.dump and all real credentials from README/docs
  (prod MinIO creds, Casdoor passwords, server IP, admin password)
- All stack secrets now come from git-ignored .env (.env.example added);
  docker-compose.prod.yml refuses to boot without them (${VAR:?})
- seed_casdoor.py: bcrypt password hashing, generated console/client secrets
- Harden infra/deploy-webhook: HMAC-verified Gitea webhook receiver
  + systemd unit + README (replaces unauthenticated deploy endpoint)
- docs/SECRET-MANAGEMENT.md: secret inventory + rotation checklist
