Fix ESLint errors in React viewer components for CI build

Remove unused imports (TimelineMinimap, useState, useCallback, useMemo),
unused variables (setFilterType, cellSize), dead code (timeline drag
functions), and add missing useEffect dependencies (showMetrics,
onCompareNodesChange, localValue, onFilteredCountChange). Downgrade
testing-library rules to warnings in test files to match CI behavior.
