feat(client): regenerate for subgraph size_bytes and storage item types

[jfrench9]

Summary

Regeneration picking up two API changes: the byte-precision subgraph size fields already merged on the API's main, and the storage-item documentation from RoboFinSystems/robosystems#1079 (transient/orphan item types, enforcement semantics for usage_percentage). Generated against the local stack at #1079's tip; if that PR changes in review, this regen will be refreshed.

Changes

• Regenerated models/ only — no api/ or facade changes; sync and async paths unaffected.
• SubgraphResponse, SubgraphSummary: new optional size_bytes; ListSubgraphsResponse: new optional total_size_bytes. size_mb remains, documented as derived.
• StorageItem, InstanceUsage: docstring updates only — the new transient (blue-green build artifact) and orphan (unregistered leftover) item type values, and a note that usage_percentage derives from durable bytes. type was and remains a plain str, so the new values are shape-compatible.

Compatibility

ADDITIVE. All new fields are optional (| None | Unset = UNSET); no removals, renames, signature changes, or requiredness flips — verified by reading the full emitted diff, not assumed from the regeneration. Rides the next minor.

Testing

just test-all run this session: 519 passed, 17 skipped; ruff format, lint, and basedpyright clean. No packaging changes, so just build-package was not needed.
