chore: bootstrap gscMy on @gsc/web-kit + PAM/JIT request flow

Initial commit for gscMy carved out as its own repo (was tracked
loosely under the monorepo's web/ which is gitignored).

What this contains:
- Auth: next-auth v5 via @gsc/web-kit createAuth (Keycloak only,
  identity sourced from claims, no admin.users writes)
- Chrome: @gsc/web-kit AdminShell — replaces the legacy MyShell.
  Sidebar JSON config carried over and mapped to DbMenuItem.
- Middleware: createAuthMiddleware. Public: /access-denied,
  /auth/keycloak, /signed-out, /api/health, /api/pam/approve.
- RP-initiated signout at /api/auth/signout → Keycloak end_session →
  /signed-out (mirrors gscAdmin).
- Phosphor-iconned access-denied + signed-out landing pages.

PAM/JIT request flow (ported from gscAdmin's pre-strip git history):
- /access page (Active + Eligible tables, request modal with
  duration slider + justification + optional MFA)
- API: /api/pam/{eligible, active, audit, request, approve/:token,
  revoke/:id}
- src/lib/{authz, pam, pam-mail, pam-mfa}.ts — same files as
  gscAdmin had before the strip. PAM tables (admin.privilege_*)
  are shared with gscAdmin; gscMy uses the same Prisma model defs.
- Top-bar widget shows active grants with countdown + revoke.

Build/Deploy: Dockerfile (monorepo-root context), k8s manifests for
my.gosec.internal, self-signed TLS placeholder, DNS A record.
Keycloak gsc-my client extended to include my.gosec.internal/* in
redirect_uris + web_origins.
