Add zero-knowledge end-to-end encryption

Summary Add zero-knowledge, end-to-end encryption so sensitive customer data is encrypted on the client before it reaches Stellarbridge infrastructure. Stellarbridge should never have access to plaintext content or encryption keys. ## Why it matters Customers with strict security, privacy, or compliance requirements need assurance that their data remains confidential even if backend systems, storage, logs, or backups are accessed by unauthorized parties. ## Requested capabilities - Client-side encryption and decryption for protected data. - Keys generated and controlled by the customer or user, not by Stellarbridge. - No plaintext sensitive data stored in databases, object storage, logs, analytics, queues, or backups. - Secure key recovery or rotation flow that does not require Stellarbridge to know the key. - Clear admin controls for enabling, enforcing, and auditing encryption. - Documentation describing security guarantees, limitations, and operational tradeoffs. ## Acceptance criteria - Protected data cannot be decrypted by Stellarbridge operators or services without customer-controlled keys. - Network captures, server logs, database records, and backups contain only ciphertext for protected fields or objects. - Users can rotate keys and recover access through a documented secure process. - The UI clearly communicates when data is protected by zero-knowledge E2EE. - Security documentation covers threat model, key management, recovery, and residual risks.
