Resolve recommended-profile Critical and High findings, retain narrow analyzer exceptions, and update the edge-broker WebSocket dependency to a non-vulnerable release.
- Add broker-related configuration classes (`broker_url`, `public_broker_url`, `auth_mode`, `shared_secret`) to support edge gateway functionality.
- Enhance `SelfserveRoute` with routes for managing self-serve wash sessions, including session listing, detail retrieval, and forced lane stop.
- Update unit tests to validate new configuration handling, session routes, and OpenAPI endpoint coverage.
- Include default environment variables for broker settings in `docker-compose.example.yml`.
Transitioned from obsolete gateway object classes (`edge_gateway_shell_action_jobs_o`, `edge_gateway_shell_events_o`, `edge_gateway_shell_sessions_o`, `edge_gateway_update_jobs_o`) to the new agent implementation (`edge-gateway-agent/agent.php`).
This commit introduces delivery metadata tracking for gateway commands, updates, and shells. Adds preferred delivery channel handling, refined validation for edge agents, improved relay management logic, and broker presence reporting. Includes schema changes, enhanced shell handling, and test coverage.
This commit introduces unit tests, E2E tests, and implementation updates related to edge gateway lifecycle management, including update handling, artifact validation, and rollback mechanisms. It also refines routing, component interaction, and backend methods to improve update tracking, status transitions, and artifact management.
