Subject: [PATCH] feat(HRT-79): alertes Telegram configurables Premium/Pro
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- telegram_alerts.py: service envoi alertes via Bot API (send_pre_race_alerts,
  build_race_alert, send_telegram_message) — gestion gracieuse TELEGRAM_BOT_TOKEN absent
- auth_db.py: migrate_telegram_columns() idempotente (ALTER TABLE + try/except OperationalError)
  colonnes: telegram_chat_id, alert_value_bets, alert_top1, alert_quinte_only
- api_v1/routes/user.py: blueprint user_bp GET/POST /api/v1/user/telegram-config
  protégé @jwt_required_middleware + @plan_required('premium','pro')
- api_v1/__init__.py: import + register user_bp
- turf_scheduler.py: run_telegram_alerts() + schedule_dynamic_telegram_alerts()
  planifiées 30min avant course (même pattern que schedule_dynamic_scoring)
  avec try/except Exception + fallback logger
