feat(gpu-service): add GPU Instance Types management page

- Card/table list of instance types per Kubernetes cluster with delete
- Create drawer with flavor picker and per-GPU resource form (CPU/RAM/storage)
- Fix unit CPU to 1 for non-acceleratable flavors; N/A memory for generic types
- Add routes and i18n across all locales
