🚀 What

• Update management and sandbox API specs
• Sandbox API spec now comes from basetenlabs/sandbox instead of blaxel-ai/sandbox
• Remove sandbox network configuration (SandboxNetwork, SandboxNetworkProxy, SandboxNetworkProxyRoute, network on create and info), which the API no longer supports

💻 How

• Point SANDBOX_SPEC_URL at basetenlabs/sandbox and regenerate with --update-specs
• The fork's spec is older than Blaxel's, so the low-level sandbox client loses process wait, filesystem copy, and filesystem tree params; no high-level SDK or CLI code uses them

🔬 Testing

• Existing unit tests updated; typecheck and unit tests pass

What changed in this PR

This PR aligns the Python SDK with updated management APIs and Baseten’s sandbox fork, removing unsupported sandbox network configuration from both generated clients and the high-level SDK.

Changes:

• Switch sandbox spec generation to basetenlabs/sandbox, removing low-level process-wait, filesystem-copy, and tree-query support absent from that fork.
• Remove sandbox network models, exports, creation parameters, and response mappings; update related tests.
• Refresh management models for intelligent-route usage and harness naming, and clarify billing date-range documentation.
