feat(gpu-service): support sliced (by-ratio) GPU instances and PV status

- Add whole/by-ratio segmented toggle to the GPU Instance form; sliced
  mode picks a VRAM ratio (10-100 or finer 1-10 when max<10), scales
  CPU/RAM by the ratio (floored, min 1), pins compute at 100%
- Availability, card Max, and Instance Type cell reflect sliceable types
- Add ready/deleting status columns for storage and storage types
