ci: create CI user directly in DB (bypasses bootstrap 409)

The auth/bootstrap endpoint fails with 409 because mcpd's startup
creates a system user (system@mcpctl.local), making the "no users
exist" check fail. Instead, create the CI user, session token, and
RBAC definition directly in postgres via Prisma.
