feat: Token Broker infrastructure (HRT-205)

- PostgreSQL dedie Docker (postgres:16-alpine, port 5434)
- 6 tables: api_tokens, refresh_tokens, token_audit_log, clients, providers, token_usage
- Init SQL + Flask init_db() mis a jour
- Systemd service token-broker (port 8783)
- Deploy script infra/scripts/deploy_token_broker.sh
- Docker compose broker (docker-compose.broker.yml)
- Health check OK: status=ok, database=connected
