[Observability] Redact secrets and personally sensitive fields from structured logs

[ayomideadeniran]

🚀 Feature Overview

Create one reusable redaction policy for tokens, passwords, authorization headers, private keys, and high-risk identifiers.

🛠️ Implementation Requirements

• Keep the work scoped to the named service boundary.
• Use explicit types, validation, safe failure behavior, and structured operational signals.
• Preserve backwards compatibility or document a migration plan.
• Add focused unit and integration tests for normal and failure paths.

🔧 Technical Specifications

Node.js, TypeScript, Express, Prisma, Redis, queues, and Stellar services as applicable.

✅ Acceptance Criteria

• Redaction applies before log output; nested values are handled; original error context remains useful; tests prove secrets never appear.
• No sensitive data is exposed through responses or logs.
• Relevant CI checks pass.

🎓 Difficulty Level

Intermediate to Advanced.
