ced4568 6b52c9e1d2 feat(platform-api): split lightweight platform service from Lab image
New platform/api/ service owns students, cohorts, curriculum, progress,
scenario attempts, and student/admin sessions. No k3s, no --privileged,
no terminal runtime — starts instantly, unlike the old identity service
which booted an unused k3s cluster just to serve roster/progress APIs.

Provisioner calls (student and admin) are consolidated here too, in
provisioner-client.js, so it's the only service that talks to the
Provisioner directly.
