ROOT CAUSE: ImageCanvas referenced props that don't exist:
- activeTool, onSmartSelect, onColorSelect were used but never declared
- selectionMode checked for 'smart'/'color' but App passes advancedToolMode with 'smart-select'/'color-select'
Changes:
- Update mode checking to use advancedToolMode instead of selectionMode for smart/color select
- Replace onSmartSelect/onColorSelect calls with onAdvancedToolClick
- Fix useEffect dependency array to reference actual props
- Add missing state/refs: currentZoom, imageRef, baseScaleRef, isDrawingRef
- Add zoom control buttons to canvas UI
- Fix tool mode indicator to check advancedToolMode
