efactor: improve deploy config handling for CPU and memory limits

- Simplify deploy config check by using single if-let binding
- Fix typo: "estart_policy" -> "restart_policy"
- Make CPU/memory limits optional in buildService (only add if configured)
- Avoid hardcoded defaults that may override container/image defaults
