fix!: keep policy mock server out of the public API

[Benoît Cortier (CBenoit)]

The package broker mock is an internal test double, so exposing it from the published server-template crate creates an unnecessary API commitment. Shared protocol fixtures also belong at repository scope rather than under one language's crate.

• move MockPackageBrokerServer into private integration-test support
• keep all mock-backed router tests enabled in the default test run
• remove the mock from the crate API, metadata, and public documentation
• relocate shared package-broker fixtures to policies/test-data/package-broker and update Rust, .NET, and protocol documentation references
