BLOB Image Support
  - View images stored in BLOB columns — JPEG and PNG detected automatically
  - Image thumbnails in the data grid, row detail, and cell viewer
  - Upload images from your photo library or camera
  - Images compressed to JPEG (1024px max) for efficient storage
  - Copy or share images directly from the cell viewer
  - Non-image BLOBs now display file size instead of garbled text
  - Large BLOBs (2MB+) handled gracefully without memory issues
