feat: deploy all stacks to shared ai-stack-portal project

- Add SHARED_PROJECT_ID and SHARED_ENVIRONMENT_ID env vars
- Add findApplicationByName to Dokploy client for app-based lookup
- Update production-deployer to use shared project instead of creating new ones
- Update name availability check to query apps in shared environment
- Update delete endpoint to remove apps from shared project
- Rollback no longer deletes shared project (only app/domain)
- Backward compatible: falls back to per-project if env vars not set
