test(phase8): add enrollment operations coverage and Winter Break registration rehearsal

- e2e-phase8.js (16/16): offering CRUD/transitions/readiness, registration open/closed
  enforcement, capacity + concurrent final-seat race through the real registration
  endpoints, the public serializer's safety, website integration idempotency (sequential +
  concurrent), adult/minor paths, required-agreement conversion blocking with version
  snapshotting, offering->cohort membership, guardian recipient resolution, RBAC, and
  confirmation ROOT_ V1/self-paced/classroom flows are unaffected.
- test-phase8-winter-camp-registration.js (12/12): the full commercial-path story with no
  payment code — website submits a real minor registration (real guardian created/matched),
  guardian agreement acceptance, a simulated admin-side payment confirmation, conversion to
  real enrollment/cohort, real account activation, an independent adult path, two students
  genuinely competing for the final seat, and a REAL Lab task completed by the minor
  student with the instructor then seeing the real progress.
- e2e-phase7.js: fixed two now-stale test assumptions the new server-authoritative
  registration-window enforcement broke (an offering left in draft that Phase 7's own test
  never transitioned before registering against it) and widened a file-allowlist check for
  the new, legitimate public-offerings-routes.js.

Regression: e2e-phase6f.js 17/17, e2e-phase5b.js 32/32, e2e-phase5c.js 29/29, all fresh-stack.
