New Audit Logging System

Sim Studio v0.5.93 introduces a persistent audit log system with comprehensive route instrumentation. Audit events now track actions across multiple critical areas:

• Templates, billing, and credentials: Full audit trails for template modifications, billing changes, and credential management
• Environment and deployment actions: Logging for environment variable changes and deployment activities
• Password and security events: Password modifications and other security-related actions

This provides enterprises with detailed visibility into user activities for compliance and security monitoring purposes.

• Enterprise member visibility: Usage limits and seat information are now hidden from non-admin enterprise members
