fix(core): resolve local client url redirects and stabilize dev environment

- enforce localhost:5174 for wheel campaign client URL in local development
- lock vite dev server ports using strictPort on admin (5173) and client (5174)
- sanitize .env.example and remove hardcoded staging domain
- configure root dev orchestration and docker multi-stage build context
