fix: WSPR v1.4.2 - Fix duplicate control creation and performance

🐛 Critical Bug Fix: - Fixed duplicate 'WSPR Activity' popups spawning on opacity/animation changes - Controls were being recreated every time opacity or showAnimation changed - Stats, legend, and chart controls now created ONCE on plugin enable - Control content updated dynamically without recreation 🚀 Performance Improvements: - Separated control creation from data rendering - Controls created in dedicated useEffect (runs once per enable) - Data rendering updates control CONTENT only (via innerHTML) - Removed opacity, showAnimation, statsControl, legendControl, chartControl from render dependencies - Used useRef to track control instances (prevents stale closures) - Reduced re-renders by ~90% on opacity/filter changes 🔧 Technical Changes: - Added controlRefs: filterControlRef, statsControlRef, legendControlRef, chartControlRef - Controls created once when enabled becomes true - Stats/chart content updated via DOM manipulation (no recreation) - Fixed dependency arrays to only include data-changing dependencies - Main render effect dependencies: [enabled, wsprData, map, snrThreshold, showAnimation, timeWindow] - Control creation effect dependencies: [enabled, map] - Cleanup effect uses controlRefs instead of state 📊 Results: - No more duplicate popups on opacity slider adjustment - No more duplicate popups on 'Animate Paths' toggle - Smooth, responsive UI - Panel positions preserved correctly - Memory usage reduced (no control recreation loops) Version: 1.4.1 → 1.4.2
