Sync clients

[herber]

Note

Medium Risk
Large auto-generated client update that expands the API surface (many new endpoints/resources) and changes the consumer_providers.deploy request shape, which could break downstream callers relying on the old signature/body fields.

Overview
Syncs the generated mt_2026_01_01_magnetar Python client with a newer API spec, adding new endpoint groups for agents, assistants/conversations, documents (incl. participants/permissions/versions), and a broad integrations surface (integrations, providers, instances, and instance groups).

Adjusts existing endpoints to match updated contracts: adds get support for callback instances, adds get_env endpoints for custom providers/versions, expands dashboard file listing filters, and renames/realigns file-link APIs to files_links. Updates consumer provider setup/deploy flow to be integration-based, with deploy now requiring an integration_setup_session_id instead of passing inline config/auth.
