All monitor detail content now lives in the sidebar panel. Delete the full-page viewDetailPanel, viewSLAPanel, viewHistoryPanel, handleDetailKey, handleSLAKey, handleHistoryKey, openSLAView, and related dead code (histogram, sparkline tooltip, detailViewport). Remove stateDetail, stateSLA, stateHistory session states. Update tests to use detailOpen/detailMode instead of removed states.
