feat: card scanning, OCR improvements, crop thumbnail, VPC enrichment
- Add scan-to-plant flow: upload card photos, OCR, VPC match on confirm form
- OpenCV CLAHE + adaptive threshold preprocessing; dual psm 6/11 OCR pass
- Regex fixes for OCR misreads: height (s→5), frost (=,„,i,l,G), density, bloom months (E→I)
- Scientific name extraction: passport section + cultivar quote strategy
- Last-wins merge so back card data overrides front card garbage
- Crop thumbnail tool with Cropper.js; cropped image shown in list and detail
- VPC image always supersedes user thumbnail on detail page
- VPC sunlight mapping: zon→full_sun, halfschaduw→part_sun, schaduw→full_shade
- Auto-set thumbnail on plant created from scan
