feat(auth): add server-controlled student and admin sessions

Replaces the Phase 2A pilot ?sid= query param with an HttpOnly,
SameSite=Lax session cookie. Gateway now derives student identity from
the session (via Platform API's /api/session/whoami) instead of trusting
a client-suppliable id, and checks ownership on every proxied HTTP and
WebSocket Lab request, not just the initial navigation.

Fixes a routing bug found during testing: the fallback route was using
'does this session own a running environment' to decide whether an
unprefixed /api/* call belonged to the Lab UI or the dashboard — true in
both places. Replaced with an explicit LAB_OWNED_PATHS allowlist of the
exact unprefixed paths the existing Lab UI actually calls.

e2e-phase2a.js rewritten to use a cookie jar instead of headers/query
params, with explicit impersonation-rejection tests added. 10/10 passing.

// Phase 2A end-to-end test — runs against a live platform/docker-compose.dev.yml stack
// (postgres + egress-proxy + provisioner + identity + gateway). Exercises the full student
// flow through the Gateway, exactly as a browser would, using two students concurrently to
// verify isolation. This is slow (each lab provision is a real k3s cold start, ~1-3 min) and
// deliberately not run on every commit — see platform/README.md for when to run it.
// Phase 2A student-flow regression, updated for Phase 2B's session-cookie architecture.
// Originally used X-Student-Id headers and a ?sid= query param — both mechanisms are gone as
// of Phase 2B (docs/PHASE2B_ADMIN_AND_PLATFORM_DATA.md §3); this version exercises the exact
// same flow through the real rn_session cookie instead, since that's how it actually works now.
//
// No framework, matching platform/provisioner/test/run.js's convention. Requires:
// cd platform && docker compose -f docker-compose.dev.yml up -d
// node test/e2e-phase2a.js
// Runs against a live platform/docker-compose.dev.yml stack. Slow (real k3s boots). No
// framework, matching project convention.
//
// This captures what was verified by hand during Phase 2A implementation (see
// docs/PHASE2A_GATEWAY_AND_STUDENT_FLOW.md §8) as a repeatable regression script — it is not
// a substitute for the manual real-Lab-image verification (node-pty, terminal, kubectl,
// scenario validation) documented there, which needs a browser/WebSocket client and isn't
// automated here.
// Usage: cd platform && docker compose -f docker-compose.dev.yml up -d && node test/e2e-phase2a.js
