fix(tests): replace abc12345 by abc1234 in TestWeakPasswordRejection

abc12345 n'est pas dans WEAK_PASSWORDS de saas_auth.py et satisfait
les règles de complexité → test échouait (attendait 400, obtenait 201).
abc1234 est explicitement dans la blacklist (ligne 84 de saas_auth.py).

Correction demandée par CTO en review PR #7 (HRT-63).

+Base URL: `http://localhost:8792`
+
+---
+
+## Endpoints d'authentification
+
+### `POST /api/v1/auth/register`
+Inscription d'un nouvel utilisateur (plan free par défaut).
+
+**Body JSON:**
+```json
+{ "email": "user@example.com", "password": "motdepasse123" }
+```
+**Réponse 201:**
+```json
+{ "message": "Compte créé avec succès", "user_id": 1 }
+```
+**Erreurs:** `400` (email invalide / mot de passe < 8 car.), `409` (email déjà utilisé)
+
+---
+
+### `POST /api/v1/auth/login`
+Connexion — retourne access_token (15min) + refresh_token (30j).
+
+**Body JSON:**
+```json
+{ "email": "user@example.com", "password": "motdepasse123" }
+```
+**Réponse 200:**
+```json
+{
+  "access_token": "<JWT>",
+  "refresh_token": "<refresh_JWT>",
+  "token_type": "Bearer",
+  "plan": "free"
+}
+```
+
+---
+
+### `POST /api/v1/auth/refresh`
+Rotation du refresh token — invalide l'ancien, émet un nouveau.
+
+**Body JSON:**
+```json
+{ "refresh_token": "<refresh_JWT>" }
+```
+**Réponse 200:** identique à `/login`
+
+---
+
+### `POST /api/v1/auth/logout`
+Révocation du refresh token.
+
+**Body JSON:**
+```json
+{ "refresh_token": "<refresh_JWT>" }
+```
+**Réponse 200:**
+```json
+{ "message": "Déconnexion réussie" }

+
+## Routes protégées
+
+Toutes les routes protégées nécessitent le header:
+```
+Authorization: Bearer <access_token>
+```
+
+### `GET /api/v1/predictions`
+| Plan    | Accès                                      |
+|---------|---------------------------------------------|
+| free    | Top 3 uniquement, 1 course/jour             |
+| premium | Toutes les courses + alertes Telegram       |
+| pro     | API complète + lien export CSV              |
+
+### `GET /api/v1/predictions/export`
+Export CSV — **plan pro uniquement** (`403` pour free/premium).
+
+### `GET /api/v1/subscription/upgrade`
+Infos sur les plans disponibles et plan courant de l'utilisateur.
+
+### `GET /api/v1/health`
+Vérification d'état du service (pas d'auth requise).

+
+## Sécurité
+
+- **Passwords:** hashés avec bcrypt (saltRounds=12)
+- **JWT access:** expiration 15 minutes (HS256)
+- **JWT refresh:** expiration 30 jours, stocké hashé (SHA-256) en DB, rotation à chaque usage
+- **Rate limiting:** 100 requêtes/min par IP — header `X-RateLimit-Remaining`
+- **CORS:** configuré pour `https://turf-ia.h3r7.tech` + localhost dev
+- **Logs d'accès:** horodatés ISO 8601 dans `logs/saas_api.log`

+
+### Get a token
+
+```bash
+# Register
+curl -X POST http://localhost:8792/api/v1/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{"email": "user@example.com", "password": "mypassword"}'
+
+# Login → returns access_token + refresh_token
+curl -X POST http://localhost:8792/api/v1/auth/login \
