Subject: [PATCH] fix(dashboard): bypass global rate limiting for internal UI
 endpoints

This commit resolves the 'Failed to load statistics' issue where dashboard panels appeared empty. The dashboard makes 10+ concurrent API requests on load, which was instantly triggering the global rate limit's burst threshold (default 10). Internal dashboard endpoints are now exempt from this strict LLM-traffic rate limiting since they are already secured by admin authentication.
