- Fixed HTML initial state: OCR toggle button has 'active', OCR panel has 'active', barcode does not
- switchTab calls setAddAssetMode() which syncs visual panels AND starts the right camera
- Previously the JS variable was 'ocr' but HTML hardcoded barcode as active — visual mismatch
- Added max-height: 85vh to modal container
- Made modal-body scrollable (overflow-y: auto, flex shrink)
- Title and action buttons stay fixed while body scrolls
- Fixes 'too tall and not scrollable' when WO details have many items
- Default add-asset mode changed from barcode to OCR
- Auto-start OCR camera when switching to OCR mode or Add Asset tab
- Camera viewport hidden entirely after photo capture (no placeholder showing)
- Retake button added to all OCR result states (found, not-found, error)
- 'Retake' resets UI and re-starts camera for a new photo
