Pull Request Overview

This PR introduces a Zod secret mixin that enables marking sensitive fields in Zod schemas as secret, ensuring that such fields are redacted from logs. Key changes include:

• Adding a new utility in backend/util/zodSecretsMixin.ts that augments Zod types with a .secret() method.
• Updating action input schemas in user and session actions to utilize the new .secret() mixin.
• Integrating secret field handling in the connection sanitization logic and adding documentation and tests to support these changes.
