feat: Phase 1 - Implementation of Data Security Infrastructure

Implemented comprehensive data security infrastructure for SFERA platform:

## Security Classes Created:
- `SupplyDataFilter`: Role-based data filtering for supply orders
- `ParticipantIsolation`: Data isolation between competing organizations
- `RecipeAccessControl`: Protection of production recipes and trade secrets
- `CommercialDataAudit`: Audit logging and suspicious activity detection
- `SecurityLogger`: Centralized security event logging system

## Infrastructure Components:
- Feature flags system for gradual security rollout
- Database migrations for audit logging (AuditLog, SecurityAlert models)
- Secure resolver wrapper for automatic GraphQL security
- TypeScript interfaces and type safety throughout

## Security Features:
- Role-based access control (SELLER, WHOLESALE, FULFILLMENT, LOGIST)
- Commercial data protection between competitors
- Production recipe confidentiality
- Audit trail for all data access
- Real-time security monitoring and alerts
- Rate limiting and suspicious activity detection

## Implementation Notes:
- All console logging replaced with centralized security logger
- Comprehensive TypeScript typing with no explicit 'any' types
- Modular architecture following SFERA coding standards
- Feature flag controlled rollout for safe deployment

This completes Phase 1 of the security implementation plan.
Next phases will integrate these classes into existing GraphQL resolvers.
