feat(gpu-service): align instance-type/flavor contract with status.detail API

- spec keeps definition fields only; observed hardware read from status.detail
- sliceable derived from slicedDetail (logical count / physical profiles)
- flat snapshot format isolated in instance-description for back-compat
- drop flavor.spec.sliceable; onceMaxRequest realigned (no ram/localStorage)
- lock compute ratio to memory ratio when coresPercentageOvercommit is false
- sliced mode submits whole cores / Gi; displayName-first type labels
