Draws a grid of image samples from a Dataset whose first Sample field is a decoded (1,C,H,W) or (C,H,W) image tensor (e.g. ImageFolderDataset) – the data-loading "preview what you're about to train on" touchpoint.

- Deliberately not unit-tested – see AttributionBarChart's note. Pixel-format conversion is plot_data.hpp's ToRgbImageBuffer (unit-tested); this only lays out already-cached GL textures.

- Parameters
-
| title | A unique ImGui child id for this grid. |
| dataset | A Dataset whose Sample::fields[0] is an image tensor. |
| cache | Texture cache to upload through – owned by the caller so it persists across frames instead of re-uploading every image every frame. |
| start_index | First sample index to display. |
| count | How many samples to display, in a fixed-column grid. |
| columns | Number of images per row. |
| thumbnail_size | Displayed width/height in pixels per thumbnail. |
| captions | Optional per-thumbnail caption drawn under each image (e.g. "true 7 / pred 7"); captions[k] labels sample start_index + k. Thumbnails past the end of captions get no caption. nullptr (default) draws images only. |
