fix(techvault): repair packaged rule MCP sources

[Brad-Edwards]

The packaged TechVault MCP sources could not express raw XML request bodies, and the Wazuh rule-authoring tool called an obsolete API path with the wrong authentication method.

This change refreshes the red and blue MCP source artifacts. It adds raw-string request body schemas and configures rule writes through the authenticated Wazuh rules-file endpoint. The pack manifest, SDL references, checksums, sizes, and provenance now identify the updated artifacts.

Validation:

• Artifact checksums and sizes match the manifest.
• Both archives contain the raw-payload schema.
• The blue archive contains the authenticated Wazuh rules-file endpoint.
• SDL versions and digests match the artifact manifest.

The exact pack test could not start in the current environment because the pinned raes dependency is not installed.
