cms: album-index thumbnail selection for pages with nested images (#210)

User Guide

Thumbnail Image Selection for Page Content

The album-index override editor now supports selecting thumbnail images from pages that use inline images (not just album carousels). When a page contains images embedded in nested rows or columns, all images are extracted and displayed in a selectable grid.

To change the thumbnail for a page entry:

1. Open the album-index editor in the CMS
2. Expand the Overrides accordion
3. Click Edit image on the entry you want to customise
4. The image grid shows all available images from the page
5. Click an image to select it as the thumbnail
6. The preview below updates immediately to show the selected image

When editing an entry, the override list and preview automatically filter to show only the entry being edited, making it easier to see changes without scrolling past other entries. Collapsing the entry restores the full list.

Focal Point Picker Resizable Preview

The focal point picker now includes a drag handle directly below the image. Drag it downward to increase the preview height for more accurate focal point positioning. The handle shows the current height in pixels.

Colour Scheme

• Sunrise (warm yellow-orange) marks the album default image
• Sunset (deeper orange-red) highlights the currently selected override image
• Star icon and "Album default cover image" label only appear for album-sourced images, not inline page images

Technical Details

• LocationExtractionService.findAllImagesInPage() extracts all images from page content including nested rows
• IndexService.applyEntryOverridesForPages() applies cover image and focal point overrides for plain pages without album carousels
• FocalPointPickerComponent gains resizable, minHeight, and maxHeight inputs using the shared HeightResizerComponent
• Override editor uses urlService.imageSource() to resolve raw site-content/ paths to displayable /api/aws/s3/ URLs
