feat(authorization): integrate with referral-service for team statistics

- Add InternalTeamStatisticsController in referral-service for service-to-service API
- Create ReferralServiceClient in authorization-service to fetch real team statistics
- Replace MockTeamStatisticsRepository with real HTTP client implementation
- Configure docker-compose with REFERRAL_SERVICE_URL for authorization-service

This enables authorization-service to get real team planting counts from
referral-service for authorization assessment and activation logic.
