fix(ci): authenticate tramiton fetch in dashboard + mcp image builds

The main deploy after #145 failed on Deploy Dashboard and Deploy MCP: because
compliance-agent (a workspace member) depends on the private tramiton-core git
repo, cargo/dx must resolve it even when building the dashboard or mcp — and
those Dockerfiles had no git auth ("unknown SSH host key"). Deploy Agent (fixed
in #143) succeeded.

Apply the same BuildKit-secret fix to Dockerfile.dashboard (dx build) and
Dockerfile.mcp (cargo build), and pass the secret in the deploy-dashboard and
deploy-mcp jobs. Dockerfile.docs is node-only and unaffected.

Refs #118.
