Implement subscription data encryption for PII compliance

Description

Context: Subscriber data includes PII requiring encryption at rest for GDPR compliance.

Current Limitation: Subscriber data stored in plaintext.

Expected Outcome: Implement encryption for sensitive subscriber data fields.

Acceptance Criteria

• Identify PII fields requiring encryption
• Implement encryption at rest for identified fields
• Add key rotation mechanism
• Implement encryption key management
• Add access control for decryption
• Support data export with encryption
• Write tests for encryption operations

Technical Scope

Files Likely Affected:

• contracts/security/src/encryption.rs - New encryption
• app/services/encryptionService.ts - Frontend encryption

APIs/Contracts Involved:

• encrypt_data(data: Bytes) -> EncryptedData
• decrypt_data(encrypted: EncryptedData) -> Bytes
• rotate_key(new_key: EncryptionKey)

Edge Cases to Consider:

• Key loss scenarios
• Performance overhead
