Expose annotation administration in Python SDK and CLI

[joaomarcoscrs]

Description

Exposes the public annotation batch and annotation job administration APIs through the high-level Python Project surface and the roboflow CLI. This closes the MCP-only gap while preserving the established upload-batch methods and legacy list JSON output.

Includes cursor pagination, batch creation and consolidation, job assignment, review transitions, Dataset acceptance, and cleanup operations. Destructive CLI commands require explicit confirmation for non-interactive use.
