feat(admin): fondation auth de l'application d'administration
Premiere brique de l'app d'admin independante : une surface /admin/*
ajoutee a apps/api, avec une authentification totalement distincte de
celle des utilisateurs.

- Table AdminUser isolee (aucune relation vers UserProfile), migration
  20260828120000_admin_user.
- lib/admin-jwt.ts : sign/verify d'un JWT admin, secret ADMIN_JWT_SECRET
  propre (jamais interchangeable avec JWT_SECRET).
- middlewares/require-admin.ts : cookie admin_session dedie, re-check
  tokenVersion, echoue ferme si ADMIN_JWT_SECRET absent (posture
  requireInternalWorker). res.locals.adminUser type via AdminLocals.
- modules/admin/ : admin-auth.{routes,service}.ts (POST /login, POST
  /logout, GET /me), admin.routes.ts agregateur monte /admin. Pas de
  signup expose.
- lib/safe-admin.ts : mapping AdminUser -> AdminUserView (drop passwordHash
  + tokenVersion, dates ISO).
- scripts/create-admin.ts : creation du 1er admin hors-bande (flags ou
  ADMIN_INITIAL_*).
- CORS : setupCore accepte string[] ; app.ts autorise CORS_ORIGIN +
  ADMIN_CORS_ORIGIN.
- Shared : schemas/admin.ts (adminLoginSchema), types/admin.ts
  (AdminUserView).
- Env : ADMIN_JWT_SECRET (optionnel), ADMIN_COOKIE_NAME, ADMIN_CORS_ORIGIN,
  ADMIN_INITIAL_* ; .env.example, .env.test.example, docker-compose.yml,
  ci.yml mis a jour.
- reset-db.ts truncate admin_users.
- Tests Mocha admin-auth.test.ts : 400 sans body, 401 email inconnu /
  mauvais mdp, login OK (cookie pose, lastLoginAt, pas de hash/tokenVersion
  dans la reponse), /me derriere requireAdmin, logout, et un cookie
  `session` d'utilisateur normal ne donne pas acces a /admin/*.
