Surface MCP Server Audit Logs in System Management UI

NetBrain currently stores MCP Server audit log data as a file on the web server, requiring administrators to access the file system directly to review it rather than viewing it within the product interface. This enhancement would surface MCP Server audit log content within the System Management page, either under the existing Audit Logs section or a dedicated sub-tab. Administrators would gain a consistent, in-application view of MCP Server activity alongside other system audit information, improving visibility and reducing the need for direct server access during troubleshooting or compliance review.
