+- Compact auto-refresh controls integrated into header with:
+  - iOS-style toggle switch to enable/disable auto-refresh
+  - Live countdown timer showing seconds until next refresh
+  - Pulsing green indicator when auto-refresh is active
+  - Icon-based refresh button for immediate page reload
+  - Informative tooltip on hover explaining the feature
