Add missing resources to CLI, MCP, and n8n surfaces

Audit all three API surfaces against the console GraphQL schema and add
missing resources: asset, audit, datum, dpia, evidence upload, measure,
obligation, processing activity, rights request, snapshot, task, tia,
trust center (with references/files), and vendor management CLI
commands; MCP tools for deletes, rights requests, trust center, vendor
contacts/services, and compliance external URLs; n8n nodes for
obligation, finding, task, evidence, processing activity, dpia, tia,
rights request, snapshot, audit log, access review, organization
context, trust center, and additional control/measure/vendor operations.

Include MCP e2e test infrastructure (testutil MCP client with API key
auth and JSON-RPC session management) and tests covering all new MCP
tools.
